It has been held annually since 1969. The Workshop is made possible by the subsidy provided by ESF. ESF organizes it, finds the teachers and location, advertises it to prospective students and pays the bills and teachers. The students do pay to attend but the amount collected does not cover the total cost, so ESF subsides the event each year to assure that it takes place. 64123 0 4206157 193 0 4206350 0 0 4206350 63095 4143255 207163 207163 3215 3215 203948 0 203948 0 203948 321153 0 321153 203948 0 0 2768 36731 76504 116003 321153 0 0 0 203948 117205 0 0 233208 0 0 0 0 0 0 0 233208 2768 36731 76504 117205 Chuck Mays or any Director listed i 638 Greenwood Circle Cary NC 27511 9197448003 chuck.mays@esperantic.org Include a letter of inquiry (to be followed by a formal proposal with a budget and a timeline.
