I'll leave it up to you guys, but i gotta say that i am bummed that i missed this year's run. people did a good job of stepping up and taking charge for my region, but GZ really seemed to be on a "flight of the bumblebee" pattern.
in my mind, it would be best to get everyone to tag themselves on the google map, then look for member concentration areas, establish a radius, and create regions that way -- then plot a starting point, loop around/through the country, and a timeline of roughly 1 week/city. obviously if we're starting in the spring/summer, the more northern areas should start, then move GZ coastal/southward as the year progresses to maximize good riding weather.
i think 3 regions is a good idea, though, but idk that there needs to be a competitive factor to it, as think the idea here is community (not competition), and that would take away from the "lets just ride together and meet each other" aspect.
that's my 2.
