This is under the assumption that i would be playing when others are near by. The intent isn't to play a show but to further my own enjoyment.
I do appreciate the point though, in that many people wouldn't appreciate the noise. I agree its always a good idea to make sure the area is always clear of any unwanting ears.

On the note of guitars such as the martin backpacker: How does the sound quality match up to the average acoustic guitar? (i understand that the quality ranges greatly in correlation to price, so lets say an average $400 acoustic?)
