I would like to stress that I was not in the area, and smoking a cigar while riding my bike!
Since this was an interstate highway, I kind of doubt it was a dirt bike...or I think they'd be trying to arrest the culprit.
I can't even see a Harley spitting out that much stuff.
Since the bike started 16 different small fires, and people reported a bike having 'trouble', I wonder if it was some sort of bike pulling off on the shoulder repeatedly with carb or fuel problems?
"Wow, I'm setting the grass on fire....better get out of here!"
Uh...none of our guys tried to install a jet kit recently in that area....I hope.
