I know alot of us stress about the diaper bag/backpack thing. I was in JC Penny today and I found a cooler (yes cooler) backpack with a mesh bag attached to the top. It has a place on the bottom for ICE and drinks (or bottles).(it says it will hold up to 15 cans of soda plus ice) Than on top of that it has a seperate compartment for sandwiches, that will stay cold due to the ice underneath. Than on top of it is a good size duffle bag. A seperate place for your keys and wallet, even a cell phone holder on the strap. It even comes in Black with yes you guessed it Lime Green Trim...(however I bought the blue one), anyway it was on SALE for $19.99. I haven't used it yet and it may get a little heavy with 15 cans of soda and ice, but I think it may come in handy. Just wanted to share
