If you have a diesel with a straight pipe (no muffler), I have news for you.
You're "THAT GUY" to everyone else in the campground. You know, the guy most people wonder when you're checking out so they can have peace and quiet again. May as well bring along a contractor generator powered by a briggs and stratton, that runs at ear splitting loudness levels and run it all day too. Or maybe unload a straight piped noisy davidson motorcycle and idle it for 45 minutes while you put your pirate costume on and rev it needlessly (in the city at every stop light) like a 12 year old with a clothes pinned playing card in his bicycle spokes. 'Cuz you know....loud pipes save lives while annoying everyone within 2 miles.
