Ha ha! I'm not worried.
No matter what I know I'll have a great time. I could do NO off-roading at all and just hang out at The Stoop and have a blast.
I could be a passenger with some people and spend a few days repeating, "OH CRAP, OH CRAP, I'M GOING TO DIE!!!" and have a great time.
Other rides would leave me sitting in the back seat thinking, "When is flight attendant coming back around with more crackers/caviar/wine" and have a great time.
I've saids it before and I'll says it again - the FUN is the hanging out with the people in the group more than the actual activity!
(Let's all hug now, ok?)
