Summer is a good time for hunting exotics as many high fenced properties have herd reduction sales then. Prices much lower.
Yes it is warm, so you hunt early and late. While the exotic hunting business was developed south and west of Dallas, there are some good places now in East Texas.
My son and I took nice Axis eating doe within one hour of my place in Farmersville which is just northeast of Dallas. It is on the north side of a reservoir where there is good fishing and good places to eat fish.Even elk are exotics in Texas and there are multiple places to shoot them in East Texas.
If you are interested, PM me and I will provide the contact information of the outfitter with whom we hunted our eating Axis does.
Have fun and best of luck to your daughter in the volleyball tourney.
In that same area, there is Hidden Lakes bird hunting preserve with nice accommodations, on site chef, etc. If you are a bird hunter (who is not?)
