Nevada's BDR is known to be a bit different than some of the others. Most interesting is the temperature differential between the northern and southern ends of the route - even as the north is still covered in snow, temps in the south reach over 100°F. For that reason, a lot of travelers split the trip into two - doing the southern route in winter or early spring and the northern bit come summer.
But not us; we're not that smart. Well no, that's not it exactly - it's just that the time we had to do the trip happened to mean we'd be doing it all in one shot. And we'd be doing it from north-to-south, just because we thought that'd be logistically easier.
At least, that was the plan.
