Hackleburg/Phil Campbell takes the cake for me as far as EF5 monsters go. However, purely from a menacing visual aesthetic goes, the Linneus MO and Keota IA wedges from last year are hard to beat.
Yeah, there's that. I don't particularly like treadmills though. They sort of do the work for me, if that makes sense. Boring as hell, too, unless there happens to be a gorgeous girl on the adjacent one (never happens).
Gotta go with '11. I think Hartford's all-time snowiest October prior to that was like 1.5" and they got a foot out of that one storm. Just destroyed records.
