I think you need to rethink your plan. My wife and I went caribou hunting in late August. I could walk around in shorts and no shirt some days. The day we left I had on everything I had brought with me. The flies were terrible at the airport.
Big piles of meat oozing blood and covered with flies.
After a short time your meat was covered with maggots. I took them off with a fillet knife. Try September if you can.

I like to do my hunting BEFORE I pull the trigger!
There is only one kind of dead, but there are many different kinds of wounded.
