I can only answer some of your questions. It costs $20 for all day. Don't go on weekends because they have go-cart crap. I don't really know their hours, I just show up and stay as long as I can, and then head home. I would imagine they close around dark, but I am not sure. Can't remember the number either.
Very tight but fun. Will teach you good corner to corner transitions. I only ever get out of 1st gear on the strait 1/8 mile or so. I am doing maybe 75ish before I but the binders on. I would love to go some time next week, no time this week /images/icons/frown.gif.
