Heres a story I copied off the motorcycle forum. A guy known as flynrider (pilot&rider) wrote it.
I'll try and give you the short version. I was returning home to Phoenix after a 5,000 mile ride to Canada and the west coast. Thunderstorms chased me all the way into Phoenix, but I hit the freeway at rush hour, so they quickly caught up. It was pouring rain and I decided to get off the jammed freeway and try my luck on the surface streets. I took an exit, but traffic was backed up all the way to the freeway, so I ended up stopped on the ramp, in the pouring rain with water up to my ankles running down the ramp. While I was standing there, I noticed a blueish glow illuminating everthing and about 1 second later the lights went out. Fortunately, since the traffic was at a dead stop, I had my kickstand down, so I didn't even fall over.
About 15 seconds later my vision started to clear and I saw that everyone had gone back to pushing buttons on the radio and reading the paper. No one had noticed me slumped over my tank. About 12 ft. away, a wooden support on a metal guardrail was charred and smoking. Since I'd been temporarily blinded and deafened by the bolt, I didn't notice until later that I had 1st degree burns on both palms and the soles of my feet. This was the lightning's exit path. As best as I can tell, the main bolt hit the guardrail and I was hit by a splinter bolt that came off the main one.
Traffic started moving after about 5 min., so I just cranked up the bike to try and make it the last 5 miles home. As I was crossing a bridge a few miles later, a bolt of lightning hit a light pole in the center of the bridge, about 50 yards from me. At that point, I was pretty convinced that God was out to get me and hightailed it home as fast as I could. My hearing returned to normal after a couple of days.
I learned two things from this experience. 1. Don't sit on a motorcycle in a thunderstorm. You're protected by the surrounding metal in a cage, but on a bike, the first thing it'll hit is your head. 2. If struck by lightning, get to a hospital fast. I didn't do this. Although my arms and legs were feeling tingly for awhile, I didn't have any apparent injuries other than the light burns. My sister (the doctor) later informed me that lightning strikes can upset the electrolytic balance in your body, and you can keel over from heart failure up to 24 hrs. later.
