I like GOX as an Xterra exclusive. There are already other events that include all Nissan makes.

It's nice to have one where you go and see nothing but Xterra's and can check out other people's rides and what they've done.

I think I might be less likely to attend if it were all Nissan- just because I could do Gone Moab which would be closer and more interesting trails.
Just my opinion. I'm not an elitist- I just hink it's cool to have 1 Xterra only event!
