I know that times are tough and getting funding and permission to go is difficult. When presenting the idea to your school administrators be sure to forward a copy of the program for the conference. Be sure to note the large number of educational sessions. There are literally more sessions than you will have time to attend. There may also be topics of interest to school administrators – such as Getting Started in Hybrid Instruction, or Program Accreditation. There are also opportunities to get free equipment. At one of these conferences a few years ago I learned about the Appion program to donate recovery machines and vacuum pumps to schools. That alone would cover the cost of your trip. If all those arguments don’t work, just tell them that I will be speaking. I am sure that will seal the deal. I hope to see you all there!
