Hey John,
Glad to hear the humpy did so well. The wing material is calf tail, and don't forget the foam for the shell back. I often forget that part and end up with a split wing royal coachman. The foam material is the same stuff that my computer keyboard came wrapped in.
I'm going up the St. Joe tomorrow to fish upriver from Avery. 117 miles for me. I googled a map and found it's 120 miles for you. If you are available, I'll be in this truck;

Hope to see you. If not, I'm planning a camp trip the last weekend of August.
