Just a cool bike in front of some cool graffiti. ((Plus, I'm experimenting with new photo filters.)) I'm totally on board with this "legal graffiti" thing most of the big South American cities have adopted. It gives the a city a hip, alternative edge - as long as the graffiti leans much more towards the side of "street art" rather than those lazy, scribbled "tags" ((Example of a graffiti "tag": Lazy, unimaginative, and appealing to almost no one.)) you see sometimes.
If I were mayor of Baltimore I'd give that a try: "Citizens, I am hereby declaring graffiti legal for the next month. But let me be clear. I am not interested in seeing warehouses covered in "East Side Crew 4 Life". I want trippy neon aliens and lush nature scenes and historical figures hilariously dressed in modern clothing. I want fantastical starscapes and colorfully absurd self-portraits and ridiculous robot vs. monster battles. And if you impress me, graffiti shall be legal forever!"
