I have attended one field day in 2014 in the state of Indiana. It was not a QDMA event. I learned more in one day than maybe a week of reading.
I think the fact this event is Free shows the level of dedication - good for yall as us Southern boys say. I am disappointed the old place closed down but we sure have it good here.
I hope you have great weather and good attendance. Since I live in Tennessee it is not possible for me to attend. I certainly encourage people in your area to take advantage of this opportunity.
Seeing things first hand is ten times more effective than reading about it.
Good luck Murdog with this event. Let us know how it goes. Photos are always nice.
