"where you might get sent to levenworth"

Nope, try Portsmouth Naval Prison, a nasty dark hole of a place...

I grew up in a Navy town and remember when the SP's would go down to the Sherriff's Office to pick up AWOL's.

Ever seen someone buck naked, dragged down the stairs and out to the wagon by the cuffs, while being whupped with a radiator hose full of buckshot?

Well during 'Nam, that's what the Mayport SP's called "Stage 1 Attitude Adjustment"!

I never thought to ask what Stage 2 was....
