I was just out near Midland last weekend and I know exactly what you mean. They are not nearly as bad here in Dallas. It is unbelievable how many of these things are running around out there. I lived there for about 5 years and never saw that many.
Once I was at a middle school helping my mom set her MS Word to use a default font size (for the third time), and I felt something on my left leg. I didn't think anything about it. I got up a few minutes later, and felt something crawling on my RIGHT leg. I freaked and pulled off my jeans and one of those GD black beetles fell out and ran off. So in order to get from LEFT to RIGHT leg, it must have crossed NO MAN'S LAND. I still feel violated.
