There have been a lot of discussions of what goes into a personal med kit.
I have a small kit in my shooting bag that is on the range with me all the time. I also have a larger bag that stays in the car and is more extensive.
The Jeep is triple black and I live in S Florida. You can imagine the inside temps during the summer.
I replace all my batteries at the beginning of Hurricane season. It is expensive and extravagant.
The question is how often and which supplies should I be replacing after being the heat of the car?
A lot of you guys have experience dealing with extreme heat. What goes and what lasts.
