I try to make it out at least three days a week. Unfortunately, school, work, and life in general tends to get in the way sometimes. >.< During the winter I'm sometimes only out two days a week. During the summer, I'm out anywhere from 4-7 days a week, usually around five, though.
As of right now I make it out every other day since I have drivers ed. But my friends shelbi who shares a lease with me makes it on the days I can't go. Then we also go on the weekend to work for about 3 hours.
