I'll bump for a tag game!
Hey Jamie, I don't now what your thoughts are on this but a photo tag game is kind of skewed towards folks with internet capable phones. Have you seen the games that use a mascot?
I just started a tag game last April. It was and still is kinda slow, but it moves along. Just depends on how many riders are in the vicinity that are willing to play. To the guy who said It wasn't his cup of tea...I can sort of relate but I have discovered a lot of cool roads, landmarks and places I never would have otherwise since I started playing, plus it gives you a destination to ride to. I'm sure everyone who reads this has gotten on their bike and said to themselves, "Now where do I want to ride today".
Have you seen these games...I play them now and then too!
Good luck with the game!
