So, if you've never heard of Gas Works Park it is a public park that sits next to Lake Union that opened in 1975 on the site of the former Seattle Gas Light Company gasification plant. The former boiler house was been converted to a picnic shelter with tables, fire grills and an open area. The former exhauster-compressor building, now a children's play barn, features a maze of brightly painted machinery.
And, it's pretty awesome and I'll let the pictures speak for themselves.
We also took a little side trip over to see the iconic Fremont troll that lives under the bridge. It was actually bigger than I expected it to be. In his left hand, he's clutching an old Volkswagen Beetle.
