The toughest part about putting on an event like GOX (traditional or Colorado crossing version) is the unbelievable amount of time spent planning, organizing, and executing it. Frankly I think Ian was nuts for doing all of the work he did, but I sure appreciated it. I doubt anyone else is willing to put that much time or effort into something like that. That doesn't mean there can't be larger national events, but they aren't likely to meet the standard Ian set. I also believe GOX is a trademark of Ian's so some other event name would be required.
