What is your position on this topic? (Me vs the workers at lowes)?

Okay, me and my friend set up a fort outside a local lowes. We hate corporate bitches. We constantly throw things at the workers that p by. We have thrown everything from toy trucks to a huge board of plywood. The workers came to our fort (off lowes property) and wrecked it one day while we were eating lunch. So we are now planning how to get them back. Opinions/suggestions?
