Let me start by saying that a group of very friendy boaters (and 99.9% are) met for a few days at Glamis for some fun in the sand, and 99.9% of these people are also great, but as you know in every aspect of life, the .01% azzholes show up. In this case, they came in late at nite, parked within feet of our rigs and blocked us in about 270 degrees. But nothing was said until the next night when they decided to start partying about 11:30 and had boom boxes that were raising the sand right off the earth. I walked over and there were 2 men and maybe 10 teenagers or early twentiers. They were polite, apologized and the music(?) went off until about 5:30 AM!!! Its too late now for payback, we pulled out a few hours later. But had I been properly prepared, how do you get even with these kind of people? I'm thinking two things; Train Horn or a cannister of tear gas rolled into thier camp? I'm looking for ideas here. Any suggestions?
