Playing an acoustic on the beach is pretty safe because the first thing people think is “bum”……
‘walk way around this guy.’
It helps to have a coffee cup with you to sit on top of the guitar case.
That keeps ’em way out there.

But in a campground, five minutes of strumming and here they come.
Approaching slowly, maybe stopping from a distance and listening, but definitely making their way to you like a sailboat tacking in 3 mph winds.
Like night of the living dead.
Coming on slowly.
But coming.
