Well, that depends on what part of Texas you're visiting. We are a great big state! I'm also in Houston and could point you in some directions here and in the surrounding areas. Are you looking for something in particular?
Look deep into nature, and then you will understand everything better.
I'll be around the Tyler area. Not looking for anything specific but I've never been to a place that sells many different types of plumeria, so I would love to visit one.
