Launch Motoamerica and prop up some teams, form new ones, and create a bunch of racer and crew salaries. Buy a 40ft ocean crossing capable sail boat, live on it, and sail to the Isle of Mann for the next TT. And dogs, save a big pile of dogs.
Build my own racetrack, configurable in 2, 3.5 and 5 miles and possibly could be ran in either direction. Preferably an area with elevation changes.
