A few weeks back Dos Lago's by us had their annual "snow day" for everyone. It actually happened on the same day the kids and I ran in Pomona. We went the first year and it was crowded and the snow was very compact so we decided not to go for a few years. We went this year and it was still the same but not as bad but the kids had a blast. They only let them in to play for about 5 mins but they enjoyed sliding everywhere.
