The Fishing Pier at Edmonds Marina is used year round by all sorts of people fishing for all sorts of fish. I've seen people catch salmon, rockfish and crab here. It's a great way to go fishing without using a boat.
The cache is hidden in a spot used by successful fishers. Expect to have muggles all around you during nice days and on weekends. The day I placed the cache it was cold and threatening to rain yet there were a couple of die-hard fishermen casting away. Most of the people fishing will answer questions and show off their catches so be friendly and inquisitive.
There are several places to park. Be aware of the parking restrictions, the Port of Edmonds has been known to tow cars improperly parked.
Hide the cache in the same spot you found it so it won't be easily muggled.
Good luck and good Caching!
