L.B.,
I drove down to Nipton and chatted with the women that work at the store and hamburger stand which is south of there, while checking out the camping facilities. They told me about that area and I read the entire information kiosk there. It sounds like you might be in that area now as I noticed you and your camper were not at you beautiful nesting site in the village yesterday. I will definitely be researching the Mojave Nation Preserve in the near future.
Good luck on your well deserved vacation. It is GOOD to have you and your family back !
