Surprisingly, our lovely city was only behind New York. I don't know about you all, but if you've ever been in NYC in the summer, walking is definitely not my preferred mode of transportation. As much as the subways are easy and the grid system is common sense, that muggy hot air that comes out from the depths of NYC's underbelly makes things unbearable. In my humble opinion, SF should have been number 1 for that item alone.
