agree, but also slightly disagree. I was here last year and alot of these geysers erupt like clock work(see Old Faithful). Yellowstone pulls in many tourists from Asia and Europe and and also urban areas of the US and there is nothing like what is there where they come from. Also you have many a placard saying geyers erupt on a regular basis around that area, and also there is a well defined boardwalk around them (for your saftey and to not disturb the area around you) that was vetted by geologists and park rangers. So some of the tourists perhaps thought it was typical, when what happened was extremely abnormal.
