I've gotten a stomach bug with symptoms that materialized after I got to work. Actually I was feeling a little off in the morning when I woke up, but I didn't consider it a big deal. By the middle of the day I was not feeling well at all and decided to start making my way home. I made it the first leg of my bike commute to the train station and then lost it in the bushes there. It was bitterly cold and no one was outside of the station, plus it was the middle of the day with few riders, so there were no witnesses that I am aware of. Took a seat in a car with a toilet in case my stomach wanted to try and empty its contents some more. My wife was kind enough to meet me at the station and give me a ride home. I could have gutted it out and rode the remaining 10 miles home, but I probably would have need to stop along the side of the road one or more times.
