Do you mean the 48-North/ Fisheries Supply sale that is
held at Gasworks park? (not Ballard)....... April 9.

The Ballard Avenue Sunday Market runs every Sunday afternoon on Ballard
Ave, (worth a visit just to see how cleaned up it is), but I hadn't
heard about a new marine sale taking place there.

Excellent swap meet and sale at the Des Moines Yacht Club, March 26.
Key is to be there *early* if you want to buy anything-----people are
usually lined up in front of the door a long time prior to opening.
