I took Ian and Elijah to a Cub Scouts sledding party in January. It was 12 degrees. But we still had fun! This is the sledding hill- it was basically a 50-foot plunge into a ravine. Fast and furious! Ian loved it, but it was a bit much for Elijah. Both times he ended up with a face full of snow. In 12 degree weather, that's hard to stomach at age 5.
Elijah got to try cross-country skiing, which he really enjoyed. He wanted to do it several times.
