First ornatus I have ever seen in Bexar county.
Adult active along roadside, grassland savanna habitat with numerous catclaw acacia, cholla and some shrubs. Animal found by Joe Furman and numerous photos taken.
On a public road in Pecos County; never got out of the way, I tried to get him (or her) off the road but he just rattled and coiled. Don't worry, I drove over him (straddled) and he made it.
