This signaled the beginning of a break from the old system, which required all revenue raised by individual parks go into the general treasury and left the parks begging for appropriations. Most of them knew that before, the money was not staying in the park, and they thought it unfair. Each year, people walk off with 12 tons of petrified wood from Petrified Forest National Park. Graffiti goons deface historic structures, such as Grant's Tomb in New York City. At Petroglyph National Monument in New Mexico, petroglyphs are disappearing into purses and backpacks.
Some difficulties do indeed result from too much loving.
Officials at other popular parks are discussing automobile bans, shuttle-bus fleets and reservations systems to regain control of the crowds. Meanwhile, politicians and entrepreneurs in some states promote legislation that would allow more road-building on park land and easier removal of minerals and timber for profit. We can only hope.
