The weekend may be starting out with snow, but there's a blizzard of outdoor activities in and around Denver that you won't want to miss. So grab your coat and gloves — but leave your wallet behind, because many of the best things to do over the next few days are free. For instance, giving back to the community won't cost you a thing at a couple of them (and with the money you save, you can buy beers at the breweries hosting the events). Keep reading for the ten best entertainment deals and doings around town.

(And Moms, we aren't forgetting you: See our list of eleven great Mother's Day options here.)
