What the deer are doing now, they will not be doing when my deer season opens in early October. Right now they are hanging out in the fields in the middle of the day. That stops about 3-4 week of Sept when the velvet comes off.
As listed above, I like to look for acorn flats and last years rubs and scrapes. Its a good time to hang stands too (despite the heat) in those places because the deer often are not using them yet (at least not if you have a high concentration of agricultural fields in your area).
