Your theory would also suck for all vacation spots. Especially on the MA and NE coast where they have a 4-6 month window. They are going to be full every weekend regardless of weather but if a model could have forecasted the Memorial Day debacle for the beaches, their bookings would have probably been less than ideal. Maybe they get filled up with introverts and such? LOL.
I saw your home thread convo. If KPIT does not get 90 but KTIM does, would that could as victory? :-)
