Where: K1 Speed (electric karts) in Irvine, Anaheim, Ontario, and Carlsbad; or Dromo 1 (gas karts) in Orange.

How Much: $25 and up depending on how many races.

Details: Just show up and race. Dromo 1 has longer races, but only 1 track and usually a longer wait to get started. K1 Speed has 2 tracks so the waiting is less but the races aren't as long.
