I'm really surprised at the reports of all the people leaving early. The weather during the week wasn't TERRIBLE, and it wasn't even as Dustpocalyptic as predicted due to a rainshower right before BM started. Sure, the roads east of 6:00 were covered in sand dunes, bumps, and pretty unrideable, but it wasn't THAT bad. Even if it IS your first time, it's not a cheap ticket and lord knows getting geared up and fully stocked isn't cheap either. And renting an RV is even less cheap. I'm curious about how people could be so turned off by the weather conditions that they'd retreat, mid-week, after such a heavy investment.
Then again, I tend to like dust-storms. It helps add to the surreal, apocalyptic feel.
