I like to watch auto diagnosis/repair videos and one of my favorite youtube mechanics is Ivan who has the Pine Hollow Diagnostic channel. He is a Russian immigrant and came over when he was a small child. He has a masters degree and is very smart. Both of his parents have phds. Anyway, in 2008 when he graduated from Cornell, he, his brother, and 3 more friends bought cheap Japanese bikes, costing from $50 to $1,000 and went on an almost 9,000 mile trip across the country and back. Their blog on adventure rider makes an interesting read I think. Some of you may be interested in reading it.
