Bugs should be minimal by August. If you can find a tiny 1 oz container of DEET, that would be all you would need. I have something like that, spray a little on my hand and rub a whole arm with it. Keeps the bugs off for hours.

If you get the Diamox, take a tiny dose: half a 125 mg tablet twice a day. Increase it only if you start feeling symptoms, like low appetite. Some doctors (using old prescription dosage info) prescribe way too much.
