How do you feel about using tactical items like mines?  I'm just looking for an opinion from people, since recently I made one for fun. It resembles a 'Bouncing Betty' and it works by tripping a switch. By the way it's built, it's usable outside and inside. Tell me what you think of it, and I will post it up soon.
