I spent a summer in college with a National Science Foundation grant doing research in Yellowstone National Park under the guidance of scientists from the Great Lakes WATER Institute.  While most of memories are of doing science experiments late into the evening, many of my memories consist of park visitors doing very dumb things like hiking without a compass and getting lost and putting little kids on the backs of bison.  Apparently, according to this article, technology is giving park visitors more confidence to do stupid things.  Amazing.
