I saw GWAR in Boise -- it was sweet! I wore a white t-shirt that ended up being red and green when the show was done. All the fake blood and green gore they hose the audience down with makes for a very good time
I've been up Cloud peak too. Very nice slog to the top and it has a great view. However, it is a popular place to backpack -- saw lots of people at the lake at 10,000 feet. But, didn't see anyone hiking to or from the peak itself.
