There are upwards of 200 venues around town doing Fringe Festival performances, some stages, some pubs, some book stores, some churches, and etc etc etc, like the place here.
As you walk around you see a standardized size for the venues saying for example ‘Venue 147’, and you can look up what’s going to be there.
There are many free events but most have tickets required. The popular ones from previous years are often sold out or you have to queue up for a seriously long time. I was way happy just enjoying the street and stopping back at that free church to see what was on.
Had I known enough I would have planned ahead!
