Got a new one: riding home at night in a flash flood with lightning, thunder, the works. A bunch of folks (myself included) were clustered under the building waiting for the storm to subside, but it didn't. And I got tired of waiting. On the way, there was a point where I couldn't go faster than walking pace due to the height of the water. Normally, I'd have been doing 22+ in that section. The water was at least two feet deep with more coming down, and of course you couldn't see the bottom, due to it being night and the whole flood part. There was a car stalled there with two folks trying to push it out of the valley. I dropped the bike and helped them push it out, then got back on and continued to home. Was thoroughly soaked--clothes, backpack, everything. My iPod and lights never skipped a beat. One hell of an experience.
