just did some math for those of you interested... these are the contest tickets by the numbers so far:
1 pair = Grand Prize
25 pairs = U2.com song request
16 pairs = AOH 10th caller promo (they played it at 6:45am EST yesterday and again in the afternoon, so they are playing 2 times/day) (ends June 8th)
25 pairs = Facebook/Twitter photo contest, ends 5pm today (not sure if eastern or pacific time zone)
These equal 134 tickets, which is less than 10% of the total tickets available (1500). Maybe there will be another 25 pair contest tomorrow (eternal optimist). Maybe they'll get up to 500 for actual fans (super eternal optimist).
Congrats to all who have won! Best of Luck to the rest of us!
