I'd prefer outdoor shows... i've been to a JON bon jovi concert which was indoor and i nearly dehydrated... it's just hot and so damned narrow (hope this is the correct word ) i hated it- and actually i like the stadium atmosphere- i actually cannot imagine only a 10.000 attd. at a BJ show *weird* but i think for they coming so early that we will have to keep up with indoor shows; maybe U2 had a bad influence with their indoor show tour- just to remind you: ticket prices were ~75€ because there were less (paying) people;
BTW: a german radio station had had an article about BJ playing the 26/27 of may i guess(?) in cologne INDOOR so i think that the other concerts will be indoor either. (they had to delete that because BJM hadn't confirmed that date at this time- don't know if it's confirmed by now...)
