Just a suggestion, but you could try Texas Parks and Wildlife Type II publis lands. Especially in the Dayton area. It's been a few years since I went, but we had both great and not so good hunts. Here is a link. Good luck.
I am in Katy, and would also like to make a few dove hunts this year. If ANYONE out there has information or needs an extra gun in the field, PLEASE let me know.
I made one hunt last year with my brother and his neighbor at a lease the neighbor found on Craigslist. Just north of I-10 near the Igloo plant. Didn't even fire my gun.
