I noticed this a few years ago and started asking around about WHY we never have 93 around here. I ended up speaking to a chemical engineer in the oil fields about it and he walked me through it.
The funny part is, you can tell when you're coming "down from the mountain" when you start seeing 93 popping up at gas stations everywhere.
