I've had large snakes in the yard when I lived in the city, along with turtles, raccoon, opossum, and skunk. This is only the thrid snake of this size that I've seen since I moved to the Hill Country.
The Hill Country is beautiful.
I lived in San Antonio for about a year and all the houses in those subdivisions were all alike - same design and no yards. Gads! They would come in with the big excavating equipment cut into a hill side, remove all the trees and erect a 100 houses or so. They all looked alike. My wife and I rented an old farm house, with a good sized fenced in yard, for the dogs, about 15 - 20 miles east up I-10 from the city limits.
