My guess is same as yours, that the signal is being centralized or forwarded by accident across the same company/producer/etc. which is why it's ignoring geography & distance. Still, I am really looking forward to see if mine will surprise!activate in later shows. XD

I bought the Vegas tickets for Saturday because Vegas is close enough for me to leave on Sat morning and come back on Sunday, so I don't have to take any time off. Seattle concert is middle of the week. New York's takes place on Sunday night, meaning if I went to that one, I'd have to take Monday off for the return flight.

(Of course, if I was still in between jobs, then this wouldn't have been a problem...)
