For some it's a profession for others it's a hobby similar in many ways to puzzle solving.
Ever tried it? It's kinda fun and it will likely scare you how easy most of the locks in your house are to pick by even a mediocre lock picker. Even that $100 high end deadbolt likely has standard pins and can be raked,bumped, or zipped open before even trying a real single pin pick.
Anyone have any lock picking experience?
