Rode with my son yesterday, ~9 miles to the bank (to get his allowance) and to the comic book store (to spend it). At one point he said 'I don't know what's specifically fun about this but just riding your bike is a lot of fun'
Then he celebrated when I was letting him punch the atm buttons by accidentally hitting the 'quick $300' button instead of the $20 button.
