Hey Gene, you can find the list of qualifications necessary and descriptions of the expected duties for mountain bike patrol and trail ambassadors on imba's site: http://www.imba.com/nmbp/membership.html. Without knowing your level of riding experience or knowledge of bicycle mechanics, I would say that those areas might be the biggest hurdles for someone new to the sport. Not ones that can't be overcome though. If you have concerns with the mechanical side, drop me a personal message & I'll see if we can't work out a night or two to tear into a bike and get you comfortable, or Moon holds wrenching classes at Healthy Habits. I'm not certain if other shops offer classes too. I'm not a deciding authority, but I would say that you just need to ride reasonably well. I'd message Splash or Dirtboy or Rage to initiate the process. Thank you for your service!!!
