Glad your looking into watching the action at RIGP. You can get the schedule HERE for the weekend. I suggest to plan on getting there Sunday when the mains start. There are a few parking lots on the north side of the track, or a parking ramp near the Holiday Inn. Bring some of the camping chairs to sit in, find a spot and enjoy the racing. There are events going on at every turn, but try to get inside turn four (middle of track) as they have kids stuff there from year to year. Enjoy your trip.
