Not sure on the others. Maybe someone will chime in. Some of the facilites in the B10 are huge and may offer more visiting tickets. I dont know, most are kind of like Lincoln, they sell out and if you want season tickets, you have to get on a rather long list.
I'm just going to guess that the first year most of our visitor ticket block will magically be pawned off to travel agencies doing around the conference tours. So many people are going to want those tickets.
