I would personally be opposed to the idea of Campsite Database or similar info being made availble on any GPS. While technology can be helpful, this info is already available and I see no good reason to increase it's scope.

This would only lead to further degradation of already overused sites, as the natural tendancy will be to make a beeline for known '5-star' sites. By not incorporating this into GPS software, those who do not have this info will be forced into camping whereever they find a site, thus spreading the impact.

NO!!!  >:(
