I was caught in a severe thunderstorm a few years ago on a very hot day. I was about 3 miles from home. The sky had taken on a dark green color, rain was very heavy with alot of water on the road, lightening was almost continuous all around (thunder was very loud but didn't leave any lasting effect in my ears). I had to slow down to ride safely but by the time I reached home I was completely exhilarated. I don't know if it was from the ozone in the air from the lightening, the danger of the riding condidtions or the cold refreshing rain or all of the above. I would gladly experience that again.
