Tim,
Here in Colorado we can get away with somewhat less octane due to the
elevation. The same volume of air/fuel is drawn in, but it is less
dense because the air is less dense. Therefore it is less likely to
pre-detonate because it is under less pressure. Our regular unleaded
around here (Denver area) is 85 octane. I don't recall the source, but
I remember reading a statistic of one point less per 1000 feet of
elevation gain.
