If anyone waits untill the last minute, that is their problem.
Maybe Buffalo broadcasters have been kind but in Rochester signal strength has varied since OTA DTV began - not in the expected ways of weather and seasonal changes but long periods i.e. months of stronger or weaker signals - so it has been difficult to determine whether or not the homeowners current antenna will suffice.
Add to that the move of some channels currently in the upper UHF band to their previous VHF locations. I for one will not be silly come February and venture on the roof, but someone's anger is going to outweigh their common sense and I foresee accidents after the cut off date.
