please elaborate
you are going to TuWeep (Toroweap) hoping to do what, exactly?
P.S. Please read the story of John Riffey, the last true jack-of-all trades ranger at TuWeep before you go.

I also suggest that you take a bag of fresh fruit and veg (or at least fruit) for the Ranger and his assistant - if they are not home you can leave it inside the screened porch (where critters cannot get at it) and also leave anote in the other door - just keep an eye open for rattlers!
I had the great pleasure of spending time with the Rangers while waiting for the tow truck for my Jeep.
