My fiancé and I got the Taxi Jam credit at Kings Dominion last year because I'm under 60 inches tall, and he was "accompanied" by me. The ride op made some comment about needing to be under 60, and then when we told her I was, she measured me and said something like, "Oh yeah you are! Well that's okay, so am I!" And she bent down so her head was below the height stick.
