I gave some offending neighbors the smoke screen treatment.
I had a bunch of inconsiderate tenters parked next to my motorhome drinking heavily and dropping F-bombs all night. I had young kids at the time and I wasn't happy.
Upon leaving early the next morning, I noticed that their tent was in close proximity to my diesel exhaust.
I cranked my engine a few time without starting it. Once I knew that the engine was flooded with fuel, I started it and revved it up real good. When they started pouring out of their tent in hungover stupor, I put it in drive an took off.
What it immature? You bet! I was too mad to care.
