Drought has been the major issue for Texas over the years. They really like damp environments, and most of the state has been incredibly dry for the past couple of decades. They're starting to rebound a bit, with the reasonable amounts of rain we've had for several years in a row now.

I never saw them growing up in Texas, but now I live in a house with a creek right behind it, and they're active all summer. I still get really excited about seeing them!

My friends who grew up in Houston find it completely unremarkable, though, due to how wet it is down there. Apparently a very common occurrence.
