I started by looking at the trend for orienteering. I was a bit surprised to see a general downward trend for "orienteering" in searches. I noticed a general upward trend in news stories about orienteering (which, I suppose, might represent more newspapers going online?).
I decided to compare two terms - orienteering and fish tacos. Looks like the terms have an inverse relationship. More searches for fish tacos, fewer searches for orienteering. I'm not sure what to make of that. But, I like both fish tacos and orienteering.
Maybe I'm being a little harsh but, it is obvious to me that people like you are bringing this wonderful sport down, you fish taco loving traitor. I may be wrong.
