We tried bringing the uncrustables down with us a trip or so ago, but man, the jelly's SOOOOO sticky, and PURPLE. I also have one kid that won't touch peanut butter (really, what genes are those?), so it was only good for the other kid, who's 4, and it wasn't worth the mess-we had to dip her in a few water fountains to get her clean. Now we stick to the 'dry' granola bars for snacks on the go at the parks-the birds love the crumbles that fall.
