Yeah I take a half gallon of frozen gatorade, bananas, sandwiches, and maybe some beef jerky. I also take a dish towel, soak it in the pond, put it in my cooler with ice, and wipe down frequently. It really helps me in the to fish all day in the 100+ temps, sculling my boat all over the ponds. Also I'll soak my hat, let it marinate in the cooler, and put it back on, makes me feel like a new man.
