I have not read the whole thread, but I just wanted to answer the question.

I sometimes busk, for the same reason I want to one day hop a freight for a while. Because it is what those that I admire have done, and it makes me be closer to the meat of the stew. So when I am in certain towns, or places, I will open the case and busk. Sometimes I get run off, other times I do alright. Marion did it around the US once.

All the best,

Mick
