Oh my Lord - this happened in San Antonio? I live 70 miles west in a small town. The only reason i go to San Antonio is Bass Pro Shop or to buy a new car. I'm sorry your trip there was so bad. I'm a 6th generation Texan and have never heard of such horrible treatment of a visitor. We do however have our share of crazy people of late and a dwindling population of the Horned Toad.
Cute horned toad! They eat a diet of ants, and if you don’t have a ready supply of ants for them to eat, you had best not keep them as pets. I never kept horned toads because of that. I do have Chihuahuan Spotted whiptails, utas, brown anoles, a big fat leopard gecko, a granite night lizard, and a pair of Tucson banded gex (captive bred). Loves me my teeny lizards!
