My girlfriend and I fooled around a couple times in abandonments, but we only got full on once, in an abandoned grain elevator (those rubber conveyor belts are very comfortable btw).
Of course, sharing such pics wouldn't be very noble, that's why we take kissing pictures instead:
1. Abandoned incinerator
2. Water reservoir
3. Abandoned train factory (we actually did some stuff there lol)
4. Abandoned community center
5. Abandoned powerhouse
6. Abandoned community center
7. Abandoned incinerator
8. Abandoned Malt Plant, during the UrbexMalt 2014 event
9. Abandoned train tunnel, Colorado
10. Abandoned barber shop, Italy
11. Under Brescia, Italy
12. Abandoned grain elevator
13. Sewers of Montreal
