If you travel into TX from NW LA, SH 21 is a nice way to go. You'll experience some of the best East Texas has to offer, including the Halfway Inn, a restored stagecoach inn from the 1800's between San Augustine and Nacogdoches.
Historic RoadMy husband and I would be glad to open the Halfway Inn and give you a tour if you swing by that way, just send a msg.
I always enjoy watching the scenery change around IH 45 at Madisonville, from the lush Piney Woods to the extreme edge of the sparce and rugged Central Texas. The whole vibe and type of things to do change just in these two areas.
I hope you all chose Texas, it's full of variety and we're partial to our neighbors to the east.
