I don't want anything to do with it. I can already see this going overboard. Hopefully this dies down in a month or two and doesn't become a thing that causes people to bump into others that don't give a damn about the game because they aren't watching where they are going for years on end. I can also see cops really loving this thing as people are going to be showing up at weird places (even if legal to go to) at all times of the day for seeming no reason and they are going to have to constantly investigating what's going on...okay maybe that last point might be a little funny.
What's also sad about it is that with the amount of traveling the game requires I don't think kids are even going to be able to play it effectively, and isn't that what Pokemon is traditionally more geared for?
Something very similar has been going on for decades with GeoCaching. (Police know about it and are cool, Park Rangers are less so, that a tupperware cache would harm their boulder.) One issue that caching doesn't have, is if these Dojos will be a gathering place for predators.
