Monthly matches-- on HW 31 outside of Chandler at the river.
The East Texas Rifle and Pistol Club off I20 Longview also has a monthly match. Its not an official IDPA match, but is run the same way. THey call them ACtion Pistol matches I believe.

Good folks-- fun matches.
I shot with them both for a few years before we moved. I got to visit with some of the folks at the State match.
