Sable Palms Sanctuary is “over the levee and through the fence” “No passport required.” There is actually a sign telling visitors exactly that.  Still, I must admit to a bit of trepidation as we rolled past the border police through the opening in the towering border fence and down the narrow gravel road.  Lots of birding sites down here saddle right up to the Rio Grande.  We and our little red Focus have likely made many appearances on surveillance cameras in the past few weeks.
