Yes, I think they flew the coop. I just called and they said there was no record of them staying there tonight. So I asked if that they had changed their minds, and that it has been reported that they are there, and that the Clocktower has received many calls, and she said: I have no comment on that.
My guess ... they'll head west on US20 and next be spotted in Dubuque, Iowa.
There are some nice casino/hotels there and a bridge directly back into Wisconsin when they're ready.
