That's actually a pretty interesting parallel to the backcountry issue. Backcountry is a descriptor as both a noun and verb. Noun: Place or thing, not unlike 'I'm heading to the backcountry in the mountains to ski as opposed to the frontside that's lift served'. As a verb to describe a style of equipment, clothing, or anything else used in the backcountry. I think there would be a good argument to be made by us, as consumers, that we buy backcountry bindings, skis, boots, clothing, and other goods used in that place commonly known as the backcountry. Now if we only had an IP attorney on the forum who would be willing to take the case...
ETA: When does TSG sue the National Park Service? They use the term backcountry for purposes of issuing permits, for one.
