I really hope this thing takes off. I know some of the other tag games took awhile to find a following so I'm hopeful this one will grow. Especially with spring approaching. Its a great excuse to go for a ride and see areas you might not otherwise explore. Not to mention meeting some other folks that share your love of riding.
To help bolster things, and since I'm without a bike for the next month or so, I volunteer to maintain an "official" Middle Tennessee Pixel Hunt Map. I'm still learning my way around Google Maps, but it's a start. At present it has but 1 lonely tag on it.
I suggest that whoever claims the tag provides as much information on the location as possible including GPS corordinates if you're able.
