My first day at prison didn't go so well. According to Google maps, there were two entrances to Springhill Institution. The rear entrance was much closer to where I was living, so it seemed the natural one to use. All the more so given that I was on my bicycle, and to use the front entrance I would have had to go down a big hill and then climb right back up again. Approaching the Institution, I was undeterred by the locked gate across the road, which clearly barred motor vehicles, but which was easy to get around on my bike. There were no signs indicating that use of this entrance was prohibited, so I figured there was no problem....
