I'm sure that some of the overloaded crowd have some set routes, but I've no idea what they might be. I have various projects that I've been working on, but not anything designed to be an introductory, 2 day trip.
The other day I was playing around with OnX to see how it differed from Gaia, and laid out an ~85 mile route from the fuel stations in Lucerne Valley to the Desert Megaphone with a couple interesting spots along the way. That might be a bit strenuous for the first day of a first trip, although a reasonable amount of the distance in it is either two lane paved or high speed dirt.
Which is why I was asking for suggestions about what people want to see or go to. We could run only part of the MT, that would be one option. Another would be to refine what I laid out in OnX and extend it to 2 days in length. From the Megaphone getting over to Michell Caverns & Hole in the Rock might be an option. Going West thru Afton Cyn is another.
