I'm not going to be living the Dakar dream in this lifetime, but I would definitely be interested in the fun/support type of participation. The toughest part for me would be scheduling. I'd have to play it by ear as dates and rates become more defined.
Unfortunately I no longer have my 640 Adventure, but it looks like I'll have a new (to me) '07 525 EXC as of this weekend (street legal and plated).
I'll be watching this thread to see how this great idea develops. Thank you, JL, for continuing to share your experience and knowledge!
