If you're ever looking for a microcosm of a city, visit one of its dog parks:

The tattooed, cigar-smoking lesbian and her pale-eyed rott; the perfect family and their perfect golden retriever; the senior citizen and his oldest living friend; the ragingly dysfunctional family and their perfect golden retriever; the woman wearing spike heels and leather pants and a yappy little rat-dog; the large, angry man and his large, angry pitbull; the neo-hippie with the macrame top, four-inch cork pumps and severe disinclination toward forcing her reality onto her dog.

And, oh yeah, the fat geek with the mutt.
