If ever there was a need for a snorkel, this picture demonstrates that need. Convoy is bunched too close together. Eating that much dust continuously, would take away from the trip. 5-6 vehicles are going to keep the dust airborne for a bit.
Getting out with friends exploring together. Being with others who enjoy your passion, and the safety in numbers factor.
Great picture Exploring areas now desolate and of few people, which once had many homesteads and small towns. Nevada is one of those places with a rich history of BOOM & BUST.
