Yeah 99 people....can't help but feel they are overdoing the hype there. I could have gone but I have no costume aside from pretending to be a changling, human/humanoid citizen, 8472/Undine take your pick. Plus I am one of those (I expect many people) who has a partner and spent the day with her and partly with my parents as well while they were in the area. Sadly none of them are in to Star Trek and my sister in London isn't fan enough to dress up but maybe saw the action (must ask her for some shots as she's in to photography).
I definitely expect USA to break that record by 10fold? more?? Maybe someone here can organise that since you don't need a Bandai to do a world record).
