Are you setting the track up at your house? If so, you are only allowed to have so many used tires on your property. A friend of mine and I were setting up a track at his dads house just inside of the Baltimore corp limit and had to change plans due to the EPA came out and told us were had too many used tires "laying around". Either way, after it's a ll set up are you going to have a CR day at your track? I think you should. :-)
