This is timely, as I am rethinking my plan based on Martin's post. (need to set up a second BOB).

For me, meds are number 1 on the list, and since the meds include insulin, some (even short term) cooling is needed when I bug out. Mostly I use those freezer packs and a small insulated cooler.

If I can bug out to a hotel, I'm OK. What is the thornier problem, is if I were taken to a "shelter" which might or might not have the facility to refrigerate insulin for a longer term. So I'm wondering about a small 12 volt refrigerator/cooler with a converter so I can set up wherever I can plug in to a wall outlet.
