Did not get the phone call

PicMonkey Collage-2I showed up at the location where a free Relay Bikeshare 101 class was supposed to start at 10 AM, the same time as the parade for the largest science fiction and fantasy convention in the USA. I had even emailed the instructor last night to make sure this was still a go.  The start time came and went. So did green people, princesses, and many people in capes, masks, crowns, and even boxes. There was even a person or two preaching. Turns out I did not get the phone call (text, tweet, you name it) that the location had been changed. Maybe they called the green lady instead.
