Since my kids are small and can't ride everything I made some cards that list the height requirements for each park. I'm planning to laminate them and put them on a ring to keep on the handle of the stroller or hooked on my backpack. Then I'll know at a glance what rides we can and can't do.
They're posted below if you'd like to download a free copy! (Be sure to set your printer to landscape before printing or they'll be smaller)
Any suggestions for other reference cards you'd like to see?
