Well, of course! If you can't wear a kilt, the next best thing is to be rootin' and tootin'(*), right? I would say "and to walk up to a water trough and cool down, there being no A/C", but I think that enough Texan-featuring romances are historical that that might actually happen.

(*) You know that movie Innerspace, where through the magic of SCIENCE Dennis Quaid possesses Martin Short's body? And they do battle against the evil technology trafficker, who is caught at one point singing into his hair dryer while wearing nothing but underpants, cowboy boots, and a cowboy hat? And who is played by none other than The Doctor from Star Trek: We Got Lost? In my head, that is the character featured in all of the Texan romances.
