When I first returned to riding after a multi year hiatus I was out on my brand new SV on my first ride out of the neighborhood.
I ended up stuck in a steady line of traffic doing about 45 through a construction zone that was down to one lane with concrete barriers to each side. No where to go in other words. Directly in front of my frightenely inexperinced self was a pulp wood truck, loaded parallel to the road - long skinny logs, mostly 8-12" diameter and pretty long. 30' maybe. One of the started sort of rocking. I'm not sure how it got loose from the chains holding most of the load down but it was totally unsecured and rocking back and forth front to back, just balanced on the end of a couple of logs underneath it that were still secured. I knew it was coming off sooner or later but there was traffic up my six so I couldn't just stop. For a couple of seconds I looked for an escape but then it fell. It hit the road, slid straight ahead for about 50' and came to a stop dead center in the road, still parallel with it. I just rode to one side, easy as you please. The car behind me was doing some hard braking and there was some screeching tires from behind him as the log was too large to run over in a car.
One day on the BRP, a buddy and me were just getting kind of warmed up when we caught up with a ranger. He was only doing about 30 mph but there was no legal passing zone so we checked up and pimped along behind him with one hand on our hips to make sure that if he looked in the mirror he could tell how perturbed and bored we were with his sub limit pace. Just as my patience was near its limit and I was about ready to give him a headlight flash or something, we went through a tunnel (a very freaky experience on the parkway as they are very poorly lit or completely unlit, like riding through empty space). As we got near the exit end, he slowed more and more and finally came to a complete stop just outside the tunnel - right in front of a 3' diameter tree laying all the way across the road, completely blocking our lane and part of the other. If we had been in front of him instead of behind him, it would have been a serious get off as we would have been just emerging from the dark tunnel into bright sunlight and probably at a somewhat elevated pace.
