I got my motorcyle today! It's a Honda Shadow Spirit 750. It's small enough to be manuverable in the city but powerful enough to get on the highway. It should be delivered sometime next week.
At this point, I would probably do very well to save my money and use the metro to get around. But I have this strong desire to have an alternative set of wheels to get me out of town, and if anything, to be able to roam aimlessly without the restriction of a rental car agency. I think it'll be a fun summer.
