Urban spelunking, urban exploration, or building hacking (whatever you prefer) is absurdly fun, intensely rewarding, and just a shade dangerous. It’s simply finding isolated, unexplored, or abandoned places, and taking a look. I don’t think the adventure is complete without taking photos to share what you’ve discovered, but it isn’t essential to the process. I’d like to take a moment to try and convince you of the incredible potential of actually stepping inside that abandoned insane asylum you pass on the highway every day going to work. I’m also going to give you a primer on how to get in to these spots, what to do once you’re there, how to keep yourself safe, and the kind of tech you’ll want to bring along if you’re intent on gathering some fantastic photos.
