Its pretty simple. here is how it goes.
Steps: (The first object is given by me the game starter)
1. The winner picks an object and posts it
2. Us riders ride out and try to find the object and take a picture of our bike with the challenge object
3. Whoever gets to it first posts up their picture in this thread and posts a new challenge object
Rules:
Take a picture of your bike with the challenge object. All photos MUST have your BIKE in them!
No National Chains (too flippin generic and common)
All Tasks/sites/challenges will conform to being legal acts (No 100+MPH speedo shots, or knee dragging, or racing)
If a challenge is not met with in a 24hr period, The Current winner will have to make a new Challenge.
No Photo Shop.
All photos must be New, taken AFTER the challenge was posted. (please dont cheat, it doesnt make you cool)
Person that comes back first with the picture is the new winner and decides the new challenge. And no you cant fill your own challenge!
Point of it - get out, get riding, go have some damn fun!
Heres an example of how it works:
Person A says the first challenge is: Your bike in front of a City Limits sign.
So i go find a city limits sign and hop off my bike and take a picture with my bike included:

So i won Person A's challenge, so now i make the new challenge.
okay Next challenge: Your bike in front of a Animal Crossing sign.
Because this is the start it can be any sign with an animal on it, think deer, horse, duck whatever you can find then post up your winning picture here with your bike and the sign and then you pick a new object post it and the game continues.
Good luck and have fun!
