I mean, I get it, we are "spoiled" in MX with groomed tracks, not liking a little mud, etc. Kinda like the Granville of the towns in my area. But...it's what we like. Besides, the waiting around only gets old when you're old...er. Spencer has a blast playing in the dirt in between motos...lol.
Kinda going with what Hershey said, at my age at least, I think GNCC might kick my arse...if I tried to go "fast" (a relative term in this context). I know a couple 3 years back we went to one of the Tomahawk Trail loops in the northern part of the lower peninsula in Michigan (a lot of good trails up there). Mind you, this after severe straight line winds and storm came through a couple days prior... I never been on the ground more in my life. Even had a head over hills to flat on my back experience when I thought I could treat a downed tree like a small whoop...lol. I had a good time and survived, but wasn't asking to go back soon...lol.
Me being a fan of air time, well, sometimes not enough to fit my fancy in the off road trail world at times. I am only kinds fast in a straight line...lol. That's not to say them dudes aren't bad arse. Amazing how they treat obstacles like flat ground. Fun to watch. That's also not to say I would never eva eva do a GNCC, just that they would more than likely be far and in between event. GPs are more my style in that arena. Not knowing the crowd, I would think it would be more of the good old boys compared to the more stuck up folks in MX. I'd guess GNCC folk would be fun to hang around...
Just my two cents and perception in not really knowing. Most I know is the Blackwater 100 river crossing and if my memory treats me right, that's not even a thing any more.... And in checking the vid out below...I guess this is a Harescramble? Yeah, I do not know the difference between a Harescramble and a GNCC. They are the same to me...
