To Tom Bliss:

Museums often have educational outreach programs that are presented offsite, frequently in schools, and they also can sponsor concerts, cultural events, and even festivals. If you like working with kids, one of the hottest new museum activities is the "overnight", essentially a slumber party in the museum, where a folksinger with storytelling skills can be the center piece--

Here at least, many schools have special budgets that allow them to bring performers in (often paid for by PTA fundraisers), and the central offices are not involved--as to the other, I've created programs that needed to satisfy state and local core curiculum objectives, and it is and time consuming work that needs the resources of an organization that is capable of working with a bureaucracy--
