Mapquest or Google Maps should get you good info; parking for the Museum is off of 16th St., Gate 2 halfway between Turns 1 & 2 takes you under the track and the parking is straight ahead. Museum admission is $10, Bus Tours are $8. They also have special tours that have additional access to normally-restricted areas; go to http://www.indyracingmuseum.org for schedules and contact numbers.
