Neighborhood park are great things, and we are lucky to have three nearby. They're used by local daycares and schools too--and not just in the summer time.
This group of kids (from the daycare which our children attended decades ago) were doing all the kinds of things they'd do in the park in the summer, only instead of grass to play, they have snow. Easier to build things with, softer when you fall too. It's great that snow suits are as warm as they are: it's rare that you see a kid who has not flung off his or her mittens who is crying with cold because the material the snowsuit is made of is so warm! Luck us!
