Hey Good Luck in the early youth hunt. Personally I wouldn't leave a deer lay too long that I planned on eating with those temperatures. I know when regular season opens, it's still fairly hot in SW P.A. so I usually skin the deer out and get it in the fridge as soon as possible. When it comes to how long before trying to recove a deer....well that depends a lot on shot placement. If it's a good solid hit, I usually wait 1/2 before tracking
