From what I know of the OP, this band, or one like it, would be right up her alley. No pressure, standard arrangements and friendly people. I don't know the logistics involved or what is or isn't available in a broader geographic range, but for myself, in Japan, I used to travel by train i.5 hrs for my sax lesson, the same length for a composition/arranging lesson, and later in Germany, about two hours for a lesson. When I began playing in a community band here, I was also commuting about an hour, round trip. Inconvenient but doable.
