3. At least one person close to you is going to freak out
It could be your Mom, your Dad, your mailman, your high school ex who now feels responsible because of the numerous times you were encouraged to climb all the way up to her bedroom window (but goddammit Julia stop making everything about you, okay?).
4. The whole "taking pictures of your urban exploring" thing is new, but also necessary
If you climbed to the top of a building and didn't take a photo, did it really happen? Turns out: yes. Intrepid climbers have been doing this way before Instagram -- Lanning, for example, started out exploring these places without bringing a camera, but has since picked up photography skills from his exploring partner and girlfriend Lindsay (and along with them, thousands of Instagram followers). Part of the draw of social media sharing? It serves as a way to document certain spaces at a particular moment in time -- like the former graffiti haven 5 Pointz, pictured above, which is currently a huge pile of rubble atop the foundation of a future condo.
