My buddy and I knocked on his door when he was passing through Ventura, Ca maybe 7 years ago. He invited us into his rig and we talked with him for several hours. He was very hospitable and even posted our pics on his blog.
When he stopped traveling in the USA the blog didn't interest me as much and I would just occasionally check in. He went through a political phase which I kind of took as anti USA so I stopped all together for a while. After his son passed and his relationship with his other son soured it seemed that it was just too much for George to handle. I can understand why he prefers his privacy. I just pray that he does whatever it takes to make right with his estranged son.
