I really hope he makes it. Years ago I heard that traveling through Central America was dangerous due to wayside bandits. At that time not all of the Pan American Highway was paved through there. I personally wouldn't even ride through Mexico, but I guess I am chicken. Mexico has the second highest level of kidnappings for ransom in the world after Colombia. I suggest getting an arrangement with a "Coyote" to post bail for you in Mexico, and make friends with the Federales. Too bad you can't carry a full auto Uzi with you.
I just back from a trip to panama about 6 months ago. Started in Napa, CA on my 1975 R75/6 the frist part of november; rode to panama; rode back through Central America and mexico; through Texas and the east coast into canada; over to Nova Scotia; and back acroos the US. On the last day of my trip I was rearended by a guy on I-80, bike was totatled and I slid into the salt flats on the Utah Nevada border.
all told 7 months 21,000 miles and one busted bike.
