It's fun to carry the "It's Friday!" energy into the commute home and go on a big meandering route finding hills to attack (Yes, up and down.) and pizza to dumpster.
Not fun is dealing with people in cars. Swerving at you in your lane, trying to grab at you and stopping to try to lecture you about how they're doing you the cyclist a favor of passing you at twice the posted speed limit on a very small road heading into a tight curve. Oh but they know what they are doing! They ride a bike 200 miles a week!
Whatever. Motorists beware of the cyclist with Saturday Night Special Handlebars.
