Bob Scott lives in OK, but I'm not sure how close he is. You might check with either Lois Hart or Michael Bouman, who probably can recommend some good speakers in Region 11. I'm sure there are many others in your region who might not be too far away from where you are and thus, keep down travel expenses.
Or if you're really pressed for a program, you can always download some of the FREE powerpoints that AHS offers on our Members Only site. Many of those are good for a last minute program!
