Sometimes you can't avoid a line (like waiting for the princesses in Toontown)
So, I packed peanut butter (either in tupperware or in a baggie) and lots of spoons every time we went to a park. When the kids (3 of them under 6 lus the 11 year old) got restless, I gave them a spoonful of PB. They ate it like it was a sucker. I took an extra baggie to hold the used spoons and wipes to clean up when they were done.
