We made this a long weekend and biked up to Whidbey Island, where we spent two nights reading, napping, and playing video games. The ride up was approximately 50 miles, as we followed the Inter-Urban bike trail to the ferry. The Inter-Urban is very nice biking (though not too scenic) where it exists; unfortunately, it consists of disjoint segments, and getting from one to the next in the absence of signs often involves educated guess work.
The ride back was about 70 miles and surprisingly tiring for all of us. The path itself was fine, so it must have been the staying up late instead of catching up on sleep that did us in….
