Threatening Phone call made by someone other than you. Or, get someone from Team Chevelle that lives near that area and have them go over there. I don't think that they would have a problem retrieving your stuff in a more "appropiate" manner if you get my drift. If I lived out there, i would certainly go over and threaten to break his legs if he did not cough up the items on spot. If you want, I will make a post on the Team Chevelle board for you.
