Those involved in urban exploration have learned to appreciate that this activity takes us to a huge variety of places; factories, hospitals, schools, theatres, churches, etc. As a result of the original purposes of these places, they tend to have very different characteristics, especially once abandoned.
This was clearly illustrated on a recent trip to a decommissioned correctional facility I explored. Since this was the first time I've ever explored a penitentiary some of these characteristics jumped out at me; beds, kitchens, cells, etc.
While I'm passionate about exploration in general, it's very refreshing to visit places that are so different from others I've been to.
