Man, if I had a dollar for every time I see one of these on freecycle or my local moms board, I would be rich! LOL
One year, we were at the zoo and saw a large extended family walking towards admissions and my DH gave the family our passes. So instead of several dollars for them to go in, they paid for 2 of the grandparents (senior discount) and one of the older kids since all the adults and the younger kids got in on the passes. They ran into us later and shared what they did!
: So now we just pass them on at the zoo.
