Rule#1 Revision #2
I think the idea of having the mascot is a very valid one, it also gives a time line and proof that your bike, the mascot and the location jive together. There is the valid point too about someone gabbing the mascot to come back later with their bike to take the tag shot, but that seems like a lot of trouble and the odds that someone grabbed the tag before you and hadn't posted it yet are just as great. That said the game would still continue, if delayed by a bit.
It is better to live one year as a Tiger, than a hundred as a sheep.
