Okay. I'm curious about the freezer bag, as that's one thing (okay...one of many - that fact that I'm lazy is another!) that keeps me from biking to the store during the summer. I worry that milk/eggs/ice cream/etc. would be warm by the time I got home. Do you carry a "blue ice" with the bag? Does it just keep the cool stuff cool? Does it scrunch up into your pannier without breaking/cracking/ruining the insulation? I've seen some insulated bags, and wondered how they would fare in a bike pannier.
