Number 2 (is that number just supposed to be the place mentioned in this thread?)
Mall of America in MN:
http://en.wikipedia.org/wiki/Mall_of_Americahttp://www.mallofamerica.com/Why: It's a huge mall, gets lots of visitors from all over the country (and some from visitors to the country).
Most of all, because there's so many shops (over 520 and an amusement park) pulled together in one place, if they could get every shop in the mall to accept them, it could be a major place for Bitcoin enthusiasts to visit, and also could introduce it to many new people, and I'm sure it would get coverage from the news if they could/would decide to do that.
Excellent Location! It is clearly a key hotspot in the local area and nation as a whole!
I like the idea about acceptance of Bitcoin across all the outlets within the mall, it would certainly increase exposure! This would be an executive decision for Mall management and possibly with something this big would be with the mall owner themselves. However if acceptance of Bitcoin in it's direct form wasn't possible then atleast bitcoin could still be spent there indirectly via the ATM once converted to FIAT. Or with our earlier idea of an intergrated debit card network which would allow direct access to bitcoin.
Great suggestion!
Number 3...
Why not do this online? Going to the mall and shoving bitcoin knowledge into the mouth of each and every person. Why not fund a bitcoin tutorial video and article and have all bitcoiners share it to everyone. Or do something creative to get the atttention of the people?
