I feel compelled to respond to this article. No one can enter and leave the wilderness without a trace, whether on foot, bike, horse, all-terrain vehicle (ATV), skis, snowmobile, or snowshoes. However, rock climbing is among the least invasive outdoor activities. Apparently, someone with a personal vendetta against rock climbers discovered that a snail population in one location might be affected by climbers. Is there anyone available to consider the effect of a single, noisy, smoke-spewing, oil-dripping ATV on a forest road?
