That is what we did yesterday afternoon after homework and chores of course. Since we have snow here in the high desert of Oregon we dug out the snow bibs, boots, gloves etc... and went outside to throw a few snowballs and play in 2" of snow.
The kids got on the trampoline and had fun jumping and sliding around, keep in mind that we have the net around ours so no falls can happen. Then we had a snowball fight. Snowball fights are not allowed at school so I am ok with them as long as the snow is soft and it is all in fun, no face shots.
Since it was snowing we all came in looking like drowned rats and had some hot chocatate and ate dinner.
Just a little note. I give my girls hot chocalate just about every time that they come in from playing in the snow because it just seems like the right thing to do.
So if you have snow go have some fun with your kids outside and release your inner child. If you don't have snow yet or won't at all make some paper balls and have a paper ball fight. Enjoy and give them some great stuff to pass on to their own kids someday.
