I've found a nice spot to play on the Common just across from the State House. This will only last as long as the weather be good, but I like to think some of the folks rushing by in their suits and heels are legislators who might be disposed to think kindly of the arts occasionally.
The other day, I ended up partially surrounded by a school group of, I'd guess fifth- or sixth-graders eating lunch on the lawn. After they were done, one little girl came up and said, "If I had any money, I'd give you some." Awww.
