I was just in east Texas last week. They say that Kilgore is Bush's favorite Texas city.
There is at least one good Reformed Baptist church, and there is a PCA church in Tyler. Tyler is about 30 miles from Kilgore, but it's all 70mph freeway driving.

This is a RB church in Longview, which is about 10 muiles from Kilgore. I've talked to this pastor a few times, and he's been to conferences at my church, but I've never been to that church.
I go to First Baptist Church in Liberty City, which is less than 10 miles from Kilgore. It is SBC and not technically Reformed, but the pastor, most (if not all) of the leadership, and much of the congregation is Reformed. The pastor is excellent. He is what I would like to be as a pastor: knowledgable of the Word, able to preach and teach, caring, loving. He was the drawing point for my wife and I.
