The gravel will be nice, you could always have a water spray wheel wash, similiar to what gravel quarrys have to wash off the truck tires before they go back on the road. Its just a concrete basin with drains with pipe running down both sides with holes drilled in it..... Just put it on the exit of the track then there wouldnt't be any mixing of the two... Cant wait to come back to the Burg any chance of having the MMSA sometime next year, or even a border war between the two series?
