For over a 1/3 of a century, The Annual Friendship Run hosted by the RIVER RIDERS MC at the Grand Canyon Caverns is a sight to see. While RV parking is available, tent camping is still the preferred choice of most participants. We have friends that come from California to Europe just to party with us and meet new friends. OLD SCHOOL bike games, great food, great music, camp fire over 50 feet raging all night, and the party continues for well into 2 days and 2 nights. You have never seen any Run like this one!!
