Hi Bob, Throughout my 16 years in museum education, I have always believed in generating my own salary, plus. Even during my time as Director of Education and Collections at the Museum of Science and History in Jacksonville, FL, I managed to present enough programs to pay my salary, plus about 20%. Admittedly, I have found this to be much easier with science than with history. People are usually willing to pay fees for million volt sparks and big flames. Now that I am back in business for myself, I definitely have to generate my own salary!
