You'll have to leave the highway, but it's a nice easy Stop and Grab available from both directions. We wanted to put this a little further East of the present location, but other caches incurred so.... here it is!
Please don't try to take it too far from its hiding spot or it will no longer be a hiding spot.
Normal desert critters should not be a problem here, but muggles are present since it is a busy location. Also, don't plan on staying here for any length of time.
Bring a pencil for the log and to record the obvious code.
