Friend of mine last weekend or the weekend before went up Memaloose with a friend to site in some rifles. The big pit was packed and didn't have enough distance anyway so they went up further. They got to a point where there was plenty of room and the snow was pretty deep. They could tell by the snow that nobody was up further, no tracks. So they set up and used the truck as a base to shoot from. After a little bit a forest service officer showed up and gave them the riot act for shooting from the road, even though there was absolutely no safety issue. The guy gave them each a $500 ticket. I realize it's the law, but seems like under the circumstances a simple warning and asking them to leave would've sufficed. Anyway, keep it in mind when you are out shooting.
