This was hanging out in a garage in rural north central Arkansas. I don't recall the exact size, but it wasn't small, although it also wasn't huge (maybe around 2" long?). I took pictures and fled the area as this is one of the scariest insects I have personally seen, so I didn't see how it traveled but it appears it may have wings folded up on its back. I think it sort of resembles a mantid but I went through all the pictures in that section and didn't see one like it. The most interesting detail is the spiked "mane" on its back.
