Mate, your story instantly brought me back to the early 90's, when I'd still go back home to upstate for summers. (I was going to college in Colorado at the time.)
I had a sweet summer maintenance job at a local park, and everyday the crew would pile into a couple trucks and ride into the village for some lunch.
There was this one guy, whose BO was un-f'ing-believable.
I distinctly remember 2 times when he squeezed in the truck, next to me, and honestly made me physically wretch. I've had the misfortune to smell BO a bunch of times in my life, but this dude was the Mt Everest of stank!
Thanks for reminding me of that!
Now I feel like I need to take a shower.
