Ok, so...somehow I came across the Colorado 500:
The Colorado 500 Online
It's basically an annual charity dirt bike run that was started back in '74. Looks pretty neat
So I thought : "Wow! With all the 4x4 enthusiasts in Colorado, we could do something like that", because that's how I am.
The idea is that we do a multi-day almost all off-road run around Colorado, for charity of course. The most logical weekend would be Labor day, since pretty much every trail is open, it's always a 3 day weekend. I'm thinking maybe to support the troops (and families), or maybe for charity in general.
If something like this already exists, please let me know

What does everyone think?
