There are maybe 2 stations within a 25 mile radius that have had 93 in the past but that was around 2006 and I don't know if they still carry it. So, I opted to run 91.

My road trips mostly consist of hitting the canyons in our foothills in the summer with some trips up to Winter Park and Breckenridge which are both at higher elevation. I should be good to go.
