They were a little suspicious of it when Kev was driving it . . . "It's gonna get us, Mom!":
J had the most fun just chasing it around the parking lot, especially when Kev got it stuck in the bushes and the batteries ran out.
ETA: Last night we took it out with my Dad's car and ran them again. On the last run of the night (of course it was the last run . . . after that it didn't work anymore) Kev ran it into a divider post on the edge of the property and bent a steering rod. No more fun until he fixes it. Shouldn't take long compared to the 3 days it took to build. :)
