They are just out there, in the woods, prairies, crossing the road...I almost hit two different ones on the same road, but luckily was going slowly enough to see them. I thought I did hit the one and we got out to check, it had gone back into the grass. The one pictured.
The one was on the way in to our destination and one on the way out. We took photos of both and they were different, one was a little larger, their coloring was different. My kids have been camping here in Texas for 10 years or so and have also seen tarantulas "out there," at scout camp, etc. and have HANDLED THEM.
