Does a hiker go to the bathroom in the woods? It might matter, under a recent federal court ruling.
The U.S. 9th Circuit Court of Appeals ruled correctly last month that parking fees were being wrongly levied in many areas of America's national forests. A 2004 law is quite specific that it is impermissible to charge fees for parking or for "general use" of the forests. But while the court's ruling was perfectly in line with the law, the real problem is with the law itself. Under its provisions, if you use the bathroom while hiking in the forest, you can be charged, but not if you use nature itself as the bathroom. Picnicking on the ground has to be free under the law, but eating at a picnic table could, at least theoretically, cost you, as could using a trash can.
The way the law was drafted, it's all about whether forest visitors are using "developed" facilities. But as the examples above show, that's a ludicrous distinction that is impossible to enforce, out of line with the procedures at most wilderness parks and ultimately harmful to the forests and their visitors.
Most national and state parks and many regional parks charge an entry fee for vehicles whether they're headed to the trail or the interpretive center, understanding full well that hikers' and bikers' activities come with costs even if they don't use the "developed" facilities. Most hikers require trail markers to guide them on their way. The heavily used trails themselves must be maintained. Anyone might need emergency rescue or medical help from rangers. And for that matter, why shouldn't a parking lot be considered a developed facility?
