1988, Merrimac River Amesbury MA. 02:00 with a friend and 2 VERY drunk ladies from local bar. Walking down dock to boat for late night ride (always told the ladies we'd go for a spin - boat would never leave the dock ) and the nit-wit I'm with decides to do a cart wheel - river was racing, pitch black night and she goes in on the upstream side and out of sight in a second. I peered over the other side and all I saw was a hand racing by, grabbed it and pulled her out.
I spent a fist full of cash to get her drunk and almost didn't get laid that night. Scared the hell out of me. I still get chills thinking about it.
