OK. I'll Denny it up. This is at an ethanol plant in Michigan. They are just finishing up with major over hauls and additions. There used to be a fence around this building but they built a new building near by and re-routed the truck traffic where part of the fence used to be.
I did this to our hangar manager. Found an air horn at a yard sale for 50 cents... we had more fun with that thing over the last couple of years. Nobody better get drowsy in their office or walk around a corner distracted. We found that you could pull the top off of a can of computer cleaning compressed air and put the horn on it, so we may or may not have gone through a lot of those. I hope nobody in purchasing reads this.
