Originally posted by ToddK Boerne, where I live is about 30 to 40 minutes to the northwest of San Antonio. The Hill Country isn't really much for hills, the ridges are around 1,800 to 2,000 feet in elevation versus San Antonio at around 600 feet. However, they are limestone and have many interesting caves and rock formations as well as interesting plants and wildlife. Around here they call armadillos Texas speed bumps.
I live in a country where the "Great Dividing Range" is mostly less than 1500m high (below 5,000 feet) and the highest peak on the mainland is only 2,228m (7,309ft).
So 2,000 foot high hills sound significant to me (but not in comparison to the Rockies and the high Sierra). It sounds like an interesting area! I heard that Armadillos had a defense mechanism (jumping when surprised) which tended to increase the likelihood of trucks taking them out. I certainly saw a lot on the sides of that Interstate, whether it was in Texas or New Mexico.
