Strange engine noise, scared the crap out of me

I did that to a guy at a truckstop once. He decided to park his bobtail infront of my rig and block me in because he ran out of parking and i have a short rig so at some stops there is JUST enough room to park a bob infront of me. Which if the guy had just moved and taken my spot when i left would have been fine. Instead he screamed at me when i asked him to move and grabbed a crowbar.

So i waited for him to go inside then taped and glued a harmonica my nephew had left in my rig to his exaust because i was out of zipties. Considered superglueing his gladhand seals to his holster too but i saw him coming back and scurried off before he saw me ####ing with his rig.

 

Darn woke coke at it again. Maybe switch to Doctor Browns?

 

Not a truck instance, but could just as easily happen in a truck with modern fairings and such, but on a trip from NY to Wis. in a friends Subaru wagon, everytime a big gust of wind, it sounded exactly like a horn blowing. With nobody around, I figured the cars horn was shorting out. Turns out, other Subaru owners said the same thing, and it was an outside mirror design that if the wind caught it just right, made a horn noise.

 

Used to happen with cheap roof racks you'd strap on top of your car.
