Mike,
What is or was the grandfather time period? I checked with OFA and it sounded like I would need to go through several hurdles. I got my 200 hour card through Dayton Fire in 1977 (OK I'm old) and I became an instructor in 1978 and I've been teaching most of the time since. Anyway, being in Dayton it sounded like I would have to go up quite a few different times and try to be a young kid again. A local Community College obviously wants to squeeze all the money they can get out of me and they only have a few items they can give PRO Board or IFSAC certs for. Like only Level 1 or Level 2.
