I've actually been involved with the conventions there and I knew the old managers since I advertise there with my business.
People from all over Upstate NY go there, already driving 2-3h from the Adirondacks area. Pulling it to PA is a 6-8h trip for many, I wonder if they'll make it.
The problem with Blue Cross Arena is that they are not authorized to cover up advertisements prominent tort lawyers and last few months new-style Christianity churches are advertising.
The JW also lost their "we will provide our own security" pass after some youngsters broke into a VIP suite and parking ownership and prices have jumped up at least 5% per year much to the chagrin of the Witnesses.
They had to renegotiate many times and the prices went up while attendance (and cost recovery) went down, Rochester has been a booming bio/medical/tech center and thus more conferences costing more and more money. Pennsylvania is cheap, I know some other conferences that have gone there, but it's easier for them since people are already flying and businesses pay to get them there.
It's a huge arena, 15k seats I think. 4k attendees is what they are claiming but in reality the attendance was 2.5k on Sunday, and even 10 years ago, when they had 3-4k people the arena looked abandoned when the Witnesses were there.
