It's kind of rare to find them close to the DFW area. Most are collected farther south down around the Austin area. Being touchy is an understatement, I had one I worked on for a few years and was coming along quite nicely until I gave it a bit of shade because of the horrendous hot summer we were having year before last, and within a week I noticed it was going downhill and putting it backl in the sun did no good at all. Needless to say it was gone after that. I won't waste my time with another. I have seen some really nice ones though. Good luck with yours if you find any.
