I'm in Wedgwood, which is a neighborhood in NE Seattle. I'm not too far at all from the University District, so I ride the Burke-Gilman Trail quite a bit. I rode it to Ballard today, then further north to the Shilshole Bay marina & Golden Gardens Park. I was coming past the Marina & heard some barking, kinda like a dog, but it was actually a couple seals or sea lions, playing on a buoy.
You can "kinda" see the buoy, in this pic, to the left of the sign, but not too well, I guess.
