Through his mailing list Red Rock Eater in late 1999, Phil Agre shared the surprising (to me) news that the National Park Service has discovered a serious problem: increasing numbers of visitors to the Grand Canyon FALL IN. The number of people who fall into the canyon (per year, I guess) is rising more rapidly than the total number of visitors...

The best theory the Park Service has come up with, is that Americans live their lives in a cloud of what Tsarren just called stupid consumer warnings, which they tend to ignore, and that because a lot of harmful stuff does in fact get taken off the market, they assume nothing they encounter could possibly be dangerous. So when they see a warning sign on the edge of the canyon they just ignore it and walk right in.
