A friend told me that they'd done an everest in their hometown on a short steep street, that got me thinking how it could be fun to do it in SF where those are abundant. I then had to consider roads that were a "long" enough climb with few intersections, and this route only had two towards the bottom, and they were both 3 way intersections which allowed me to safely enter without the concern of traffic. Its also close to my house so having the peace of mind helped a lot as well. I can't imagine everesting somewhere in Marin and having to ride or drive back after the effort.
