Evan... the trainer is asking her to use her property... I think that is different than a "club" hosting and inviting a speaker. I agree with you completely but this person knows Barb, and wants to use her property, due to the location. So for him it would be "BYOB".... bring your own birds. LOLYou're welcome. I hope the event is a success. For what it may be worth, I think you'll find most pros will require some things of anyone hosting a quality seminar, including the items mentioned; birds, guns, holding blinds, et al. It's much like hosting a hunt test or field trial. Grounds and equipment are largely the responsibility of the host.
What most pros who do seminars usually provide are handouts, and bring demonstration dogs, personal training equipment, sometimes a white board & markers to diagram drills, maybe orange flags to flag out their chosen drills in preferred locations on the grounds. I bring books & DVDs for those who desire to purchase them at the event. We do book signings each afternoon during Q&A.
I admire you for taking this on. I think you will be glad you did, even though putting on any event of this type is a lot of work.
