I wouldn't want to hear it in the parks but at a cabin resort or campground, sure. I think guitar etc. singalongs around a campfire in a campground is a greatr time.  In the BW or Q I think it would be out of place.

I was backpacking solo in Glacier National Park years ago and deep in the backcountry I heard a flute in the distance.  I was headed toward one of the Chalets they have in the park and as I got closer it got louder.  Sure enough I came upon a pretty young woman who worked at the Chalet sitting on top of a boulder playing her flute.

This was 1985 and I still remember her name - she gave me a watercolor of the sunset the next day and signed it "Adele".  Cool chick from Oregon.
