If your gonna hunt the west - southwest end of Wright Patman, I would make sure you scope out the place and a few maps of the area before turning dogs loose ( especially long range dogs ) ...
Alot of the Corp land runs into private land and management land... Several of the private land owners are known to be not so friendly...
Also if you go in on Mud Lake, if your dogs cross the river, either be ready to swim or make a long trip around to get them... Its a long walk back to the truck and atleast 30 - 45 minutes to drive around... Alot of private cabins and leases across the river...
I havent hunted much of the east - northeast side, but ive always been told not to go without a boat, or you may be in trouble..
