Where in Duluth?

The park at the end of Park Point!

Nope!

Gilligan's Island!
(couldn't resist)

Garfield Docks, by rail sidings, near the High Bridge?

Dave is slightly warmer than the rest, but still incorrect.

The marina area in the Morgan Park/Riverside area? I can't remember just how far out it is, might be further south, but before the Oliver Bridge.

Edgeways has it!

Spirit Lake Marina & RV Park in Duluth's Riverside neighborhood.

whoo hoo

Up your butt and three doors down? 

Oh, darn. Edge already won. 

(continuing my threadjack spree: does anyone of my vintage remember the above-quoted insult?)

I thought of the Gary marina on the way to work yesterday but I guess I was off by several miles.  You really stumped us on this one.  Nicely done.

It looked familiar, but I just couldn't place it. My daughter and I went canoeing by the marina

Vicarious, ours was "Up your butt and around the corner."

Oh, and nice boat picture, etc, etc.

Ours was, "Up your butt three blocks to the right."
