Google Blog Search - Algorithm Insanity?

This isn't really Solaris related as much as computer science related, but today I experienced a very strange behavior from the great Google. One of my hobbies is archery, and I live in the Rochester, NY area. So, I was searching blogs on Google with the following string: "rochester NY archery". Seems pretty benign, right? Apparently, it's more like looking for Dick's Sporting Goods at www.d_c_s.com.

The number one hit for Rochester, NY archery is: "Club Intoxicated Girls". Actually, almost all of them were blog spam hits. That's incredibly frustrating. It's also a bit surprising because in my experience the SPAM heuristics in Gmail are second to none. Interesting times we live in.
