Spin off from another post....we're going to do a day trip to a beach. I think we have a beach bag that will fit all of the towels and toys but it would probably be helpful to find a cooler that is more of a backpack style. It just needs to hold snacks, drinks and lunch for 4. Does anyone have one of these they would recommend? I figure that our beach bag, bag chairs and tent all would go on our arms and this would be one way to maybe make it a bit easier to carry at least one part. Our fold-able wagon doesn't do well in the sand.
