Yosemite, it seems, with its abundance of visitors, has an equally abundant number of questionable decisions made each year. One such example took place my first summer in the park and has just been recounted in the book, "Shattered Air." It details the brilliant idea of some hikers to climb Half Dome during a thunderstorm.
A second book, that has been around for quite some time, explores the notion of how wild places should be managed. That one, "Mountains Without Handrails" by Joseph Sax is a quick read with lasting impact.
And, since bears were mentioned, my favorite, "It is not my fault" story was one where a fellow left food in his car. Bear broke into the car, tore it apart. Man sued NPS and the government. The case went to trial and the judge brought it to a quick conclusion. He asked the plaintiff if he was a US citizen. "Yes" Did he pay his taxes? "Yes" "Well then," the judge replied, "The bear is yours. Case dismissed."
