I take issue with saying commercial packers as a group are "naughty". I personally know some very environmentally conscious packers. Many commercial packers are a lot more responsible than private horsemen, but then there are responsible private horsemen too. You may not agree that horses should be allowed in the wilderness, but do not blame the packer. He is just out there making a living and doing it with permits, paying lots of fees, and doing it legally.

I would put near the top of the list the self absorbed gal who put up her illegal "art work" all over the national parks.

Also, those in Congress who keep cutting back funding for the National Parks and Forest Service.
