Mike and I went sledding a lot back in the day. We spent a lot of time up Bogus Basin Road where we found a good run. This day I was there with Mike, Jeff, and one of Jeff's friends from work. I had a bunch of small hairspray cans from work that were being thrown out - and they made great explosives when they were thrown in a fire ( ask Rob about this one ).  So we built an igloo because were were just overgrown kids and built a fire inside. Tossed a couple of cans in the fire and waited.... Mike definitely loved blowing things up.
