On Monday and Tuesday, both warm winter days, my grandkids and I drove by Central Park numerous times while running errands. Not the famous 843-acre Central Park in New York City, but the Central Park in my hometown, around ten acres in size. Each time we drove by, we saw children sledding down the hills at the western side of the park.

“Can we go sledding there?” Evan, the nine-year-old, asked each time we passed it.

“If you bring your snow pants with you tomorrow, I’ll take you sledding,” I said. “But it’s supposed to be below zero in the morning.”

On Wednesday, the grandkids came with their snow pants, and the morning temperature was actually fourteen degrees, so after breakfast we stowed the sleds in my van and went sledding. I wore long underwear under my jeans, thick wool socks inside my boots, and a wool sweater under my down coat. To complete my winter ensemble, I donned a thick stocking cap, slipped my hands into a pair of lined mittens, and wrapped a scarf around my neck. But I knew it wouldn’t be enough, and that I would be cold while standing on the hill in the park as the wind circled around me.

“What if they have sleds there we can use?” Evan asked as we drove to the park.

“I don’t think so,” I said. I didn’t believe the city would spend money to provide sleds, only to worry about them being pilfered or broken. But when we arrived at the hill, there was a rack filled with sleds and topped with a tiny poem: “Use a Sled, Return it When You’re Done and Everyone Can Have a Little Fun!”

I’d been the one with the jaded heart, but my city’s parks & rec department had faith in its young citizens. “Look, Evan,” I said, pointing at the sign, “you were right.” My grandsons mostly used their own sleds, but occasionally borrowed one of the saucer sleds from the rack.

Peals of laughter and shouts of joy filled the air as they sped down the hill. I pulled my phone from my pocket to take some pictures and to look at the time — only five minutes had passed and I was already freezing. At that moment, as if to mock me, Old Man Winter exhaled a powerful gust of frigid air. I huddled next to a pine tree, but the narrow trunk did nothing to protect me from the wind’s icy breath. I wanted to go home, but anything less than a solid thirty minutes on the hill, and my grandkids would be disappointed. They were having a great time.

I decided I had two choices. I could stand on the hill and freeze, or I could hit the slopes. I placed a blue sled at the top of the hill and looked down at it.

“Nana, are you going to sled down the hill?” one of the grandkids asked.

“Yes,” I answered. I gazed at the sled and remembered how much I loved sledding when I was young. Plus, there were no adults around (like my husband) to ask, “Do you think that’s a good idea at your age?”

With grins on their faces and anticipation in their hearts, my grandsons waited to see Nana “bomb” down the hill. They knew I could do it.

Successfully, but not too gracefully, I lowered myself into the sled. I pushed off with my hands and raced down the hill, bobbing up and down on the slightly uneven terrain. By the time I used my feet as brakes to stop the sled before reaching a line of trees along a frozen creek, I felt much warmer.

Was it the thrill of the ride that pumped blood through my veins and warmed my body? Or was it the memory of getting a toboggan for Christmas as a girl and using it to sled at Whitnall Park throughout my childhood and teenage years? Either way I was ecstatic as I walked back up the hill with my sled in tow. I wasn’t cold anymore. The key to being outside in winter is to keep moving and have fun.

I went down the hill many times. I felt ageless, still capable of doing something I did when I was young. Dopamine filled my brain, and I was over-the-moon happy.

We stayed for forty minutes. On our way back to the car, Evan asked if we could come back in the afternoon.

“Sure,” I said, and I meant it. I wasn’t just saying it in the moment, figuring I’d find a way to back out later on. Sometimes we do that as adults. But like my grandkids, I wanted to go sledding again, even if it meant the dishes didn’t get done or supper would be late.

I fed the boys lunch then took them to the library for a kids’ craft hour. I went to the grocery store for ingredients so I could make chicken enchiladas after our second round of sledding.

We returned to Central Park just before three o’clock, and stayed for more than a half hour. This time I didn’t wait to get cold. I grabbed a sled immediately and began zooming down the hill, loving the speed and the winter’s air that filled my lungs, caressed my face, and returned me to my youth.

Sledding with my grandkids was the most fun I’d had in a very long time.

I made a New Year’s resolution to behave like a child more often.
