Strangest thing I ever found while riding was a dead body of a man.

Apparently he was running due to the jogging suit, suffered a heart attack and collapsed then fell down an embankment where cars could not see him from the road, but I could riding on the shoulder. He had been dead for several hours before I found him. I wasn't sure when I first saw him if he was dead so I approached off the bike and yelled at him but no response, so I touched him and he felt cold, not breathing, no pulse, and was staring blankly, so I followed my steps out so in case he was killed the scene would be undisturbed as much as possible and flagged a car down who called 911.
