Not a building, but a boat!

Yesterday's photo talked of Riding the Duck, the zany land/water tours. This post may be even zanier, and we have Captain Tristan Shout (see yesterday's post) to thank for this bit of info. On Lake Union there are houseboats, floating homes, and some buildings along the shore. The Lake Union Crew Club in the middle looks like a permanent building, no? No! It's a boat! Its owner installed propellers in the rear, and to maintain its boat status, it has to be a boat once a year, i.e. break away from the shore and sail over Lake Union. That would be fun to see....
