Looking west from Pigeon Key in the Florida Keys.  Pigeon Key is about three miles from Marathon,  Florida.  It is accessible via the old railroad/highway bridge paralleling the aptly named Seven Mile Bridge.  It’s a brilliant walk, I’ve done it many times, but I tried it on a bicycle this time.  Not recommended.  The bike goes too fast to enjoy the view and the expansion joints on the road surface seem to think they’re supposed to be crossties.  Walk, and wear a hat.
