I just received a thick envelope from the Sierra Club mailer, with 10 different pieces of propoganda. The usual stuff like pre-filled out petitions for you congress people. BUT what was most disturbing was the map of Yellowstone Park showing habitat threats to Grizzly bears. It shows, 10 pictures of motorcycles surrounding the parks with 16 bulldozers(road expansion), 7 chains saws (timber) and 8 oil wells. All apparently depicting the threat to the bears and Yellowstone. Now I dont know for a fact , but I highly doubt there are 10 OHV/ORV riding areas immediately surrounding the park. It is an over simplification of supposed threats, it makes me puke.
