I took my new ND400 filter out today and got some shots. I also took my new 18-200 lens, although this was taken with the 18-55. This is about a twenty second exposure. Next time, when there isn't snow and ice, I'll try to climb down a little to get away from the trees in the foreground.
And I also stumbled on to several hiking trails. When the ice and snow melts a little I'm going to explore them more.
