I met and wheeled with Grandpa Bob my first year in Moab. A very cool guy who had a passion for his VX and wheeling. At 75 years of age he would attempt things that most wouldn't even think of. My first year in Moab GB signed up for every trail that I did and taught me a lot about the capability of the VX. As far as I know GB is still the only VX to complete the Rubicon trail...and he took no bypasses.
You may even see some similarities in his and my wheeling style...
