Avi,

I went last year on July 31st. Trail Camp overnight is pretty cold even at that time of the year, so I was glad I brought my 15F sleeping bag.

For the clothes, what you have on your list is good.I also brought a pair of rain pants. Thunderstorms are common at that time of the year, and you don't want to be soaked as the temperatures drop overnight.

Have a great time.
