Hey all, This saturday for the 4th of July my friends and I will be heading to Grand Haven Beach which is about an hour drive from my house, arriving at around 10am and staying all day until fireworks at midnight. It's supposed to be 78 degrees outside on Saturday, and probably a lot warmer inside the completely black suburban I will be driving. I really don't want to keep the P3 on the beach with us as we sometimes like to go for walks or swim and it would be easy for someone to steal $2500 worth of stuff. However, I also don't think leaving all my equipment in a hot car for 10 hours is a good idea either. My thoughts were that I could maybe put the backpack in a cooler and then layer a thick insulated blanket on top with ice to keep it cool, or I could bring a 12V battery and wire it to a few fans to keep on in the car. Any and all suggestions would be great, thanks.
