The country is rolling hills, some areas have deep canyons and draws, according to where you are in the hill country.
The birds roost mostly in the live oak trees or native pecan trees along the river and creek drainages. They usually roost in the same area nightly, so ask where the roost areas are first thing. Don't seethe up right on the roost, if you do a bunch of shooting there,they will pack up and go somewhere else, usually on someone else,s property. And don't ask about hunting his property unless your dropping $100 bills from your pocket. Try to find the food plots, they will feed there daily, you just need to find out when. Also there will probably be feeders scattered over the property, get between the roost and a feeder and set up, makes you feel like a good caller sometime.

Get a coyote howler and learn how to use it, best device for roosting birds, morning and evening. The country will be open, don't try to get to close on the birds, they will see you. And the last piece of advice, don't be afraid to call, these birds are very vocal, get loud and proud.
And if you really want to have some fun early in the season, use a Jake decoy and gobble. Nuff. Said.
