We spent the first year in Texas traveling around to get the flavor of the various locations. We spent a month each in the Hill Country near Kerrville, on the Gulf Coast near Rockport, and in the Rio Grande Valley near Mission. All was nice EXCEPT for the RGV area. It's one big, long, graffiti covered, congested city, and had absolutely nothing to offer. People that like it tend to enjoy shopping and dining out, because that's all there is to do there in my opinion. In fact, we left there before our pre-paid time was up.
If you like fishing, the best locations would be the Gulf Coast for salt water fishing, and the Hill Country or Piney Woods area for fresh water (although it's a bit colder in the winter months). If you visit any of the Texas state parks, you can fish without a license either from shore, or a pier. If you wade, or use a boat, you have to have a license.
