I haven't had much time to post lately, but I have been looking at some packing lists for conventions. Here are two I've found really helpful:
Dragon*Con Packing List - This list has con-specific information and suggestions. Very comprehensive and thorough.
The Pretty Much Ultimate Convention Packing List - Another comprehensive list for conventions in general, with a few things not mentioned on the Dragon*Con list, and a bit more of an eye toward simplicity.
Today, my roommate and I went to Harris Teeter and purchased some foodstuffs. Then I packed some of the foodstuffs. My packing was glorious. Then I realized we'd put all the yogurt in the fridge, and I hadn't left room for it in the cooler.
Solution: second cooler. May purchase tomorrow.
