Thanks for the comments sof far:
* Riding a bicycle could get tough.
* Comment re: shadows, averted eyes, randomness noted. Aesthetically, I don't mind the blocked shadows, but I see your point. The randomness was primarily because the sequence of the images were chronological, based on my visit. The averted eyes - my timing was off on some (too slow to focus - so some were able to avert their eyes.
* Good catch re: rich areas. I was obviously a visitor going from one tourist spot to another and some local neighborhoods (local cabbie as guide), so my experience would have been guided by my pre-trip research and my local cabbie's experience. These images were representative. So, while I'm sure there were ritzy hoods around town, they certainly were well-kept secrets. Never thought about that point, but you're right.
