Gary;
On the 11th of September I will also be heading to Idaho to visit my kid brother and his wife. He is the manager of Hayburn State Park about 35 miles south of Coeur d'Alene.
I've always flown out to visit but this year I will be driving and plan to do some exploring. I've fished the St. Joe several time but would like to check out the North Branch of the Coeur d'Alene River.
The North Idaho Fly Caster's have their meeting on Thursday the 18th of September at the Best Western Plus in Coeur d'Alene. I plan to attend Ron and Kat. http://www.northidahoflycasters.org/About%20Us.htm
Maybe you will be settled in by then and we can hook up for some fishing.
