Awesome. That must have been cool seeing the fireworks. Its a pretty unique view of south Puget Sound, the Kitsap Peninsula, and the Olympics from up there.
Cool. It sounded like you guys had climbed the corner of the pillar, but it appears you were pretty right on. Nice work getting it in early season. Its a great route!
Throwing rocks and yelling at them seems to do the trick. If not that then a modern firearm used in "self-defense" would probably make them leave you alone.
