Silver ('08?), single rider with white alpinstar? jacket, passed me on I-15 just east of Mesquite, NV while I was trailering my '08 back from the start/finish of a 900 mile ride to Arizona. (I don't normally trailer to/from a ride, but I was with a co-worker who rides a Honda 750 Shadow, and has to stop every 125 miles or so).
