Amanda's right, the feedback fro homeschoolers is very important to us. A great way to maximize your time and money at a fair is to get tapes of the speakers you can't attend workshops for, or the ones you don't have any brain power left to comprehend. That way, you can listen to their messages when you can focus. I think they have gained a lot from these experiences. My question is similar to Kathy's.
Shorter workshops are tough.
Usually the fair organizers will come around and ask for feedback - but not always in a written way. Truthfully, I wouldn't have time then to respond in writing. Asking me later on a written evaluation would be ideal. Keeping the admission price down for attendees helps too. Most places offer help and services.
