Tonight someone posted a fake announcement about the band being in Zagreb already but after a short while it came out as a hoax (I can say that some band members are still very much in the usa at the moment)

I think the body clocks to adjust with local time is a necessary thing for people not used to travel too much or maybe for people who's work is 'dangerous' or with important responsability - but the band is traveling around the world for 3 decades so much that they don't really need that anymore , they adjust very fast ..... When they arrive in advance somewhere they usually have a reason like press or tv etc they cannot move somewhere else it's never because Jon want to check the lights .. He likes to keep things under control but not to that extend.
If you ask my opinion on this I would say that the guys will arrive between monday night or tuesday
