Friend and I will be in Keystone area mid June riding around... We were offered off road training by someone, who is wiling to come to the area (lives in southern CO) and do the class (level 1 and 2) there if we can find decent location. Paying small fee for using it is ok... There will be 3 of us (third person joining) on big adv bikes plus the instructor. Any location suggestions would be appreciated, ok if within 60-100 miles. Thanks!
