I read a little more on the New Mexico thing and LE keeps saying that the story does not seem to fit the evidence.

On Nick's post, we have spent quite of bit of time in SE AZ birding and the stories, trash, water bottles, etc. up in the hills point to a lot of movement. Similarly, birding on the Lower Rio Grande exposes one to some interesting folks and stories, not to mention recommendations from the local Border Patrol that it was not wise to be walking where we were.

We should listen carefully to the folks living the borderlands.
