I recently saw my 4th major car museum, my ranking ( )

1. Garlits, very race car drag oriented, suggest approx 2 hrs, Fla
2. NHRA, very race car, not just drag, suggest 2 hours, LA
3. Harrahs, wide selection, exotics, and 100's of rare cars 20's up quite impressive, include some racing cars, would recommend , suggest approx 3 hours Reno NV
4. Petersen. only two real race cars, seemed to have more effort devoted to LA history and "hot wheels", was very disappointed, can be seen in 1.5 hour

At lot of the above is dependent on how fast and how much one like to read.

Anybody like to comment or suggest others I'd like to add to my list for future visits?.
