Removing Bridgestone/Firestone tires. I spoke with them at AIMExpo and they cleared it up. It was some story about some land in TN they set aside then prohibited any kind of motorsport recreation on. Turns out they did donate the land but then the agency (State of TN?) imposed those restrictions, not Bridgestone/Firestone. They used to to tire testing on the land and they're not allowed to do that anymore either! Beware who you give your land away to I guess is the lesson!
