Its funny because on my commute to this job (I have at least two, sometimes more; plus grad school) I never take the same route to work as I do home. Its only a quick shot downtown, so I will cut straight there down this sidestreet that the city is working on* on my way there but on the way home I will take a slightly more roundabout way because riding downtown at 9:30-10pm is SO relaxing!
*That sidestreet that the city is working on is an interesting project. Mainly because it has been 2+ months with no discernible change in the road. There is a 40 foot stretch that there is no pavement, just dirt and rocks. Thats a fun part of the commute...
