RE: Grouse, What's the secret to bagging these "fast flyers"
Haha! The secret to grouse hunting is to keep after them. You'll flush a LOT more than you'll shoot. Do you have a dog or go it alone? I swear grouse can fly through a tree trunk, and they know how to put every single twig between themselves and you.
Do a search on the ruffed grouse society (both in the US and Canada). They have some good resources on their websites and some free literature available that gives a good review of grouse habitat.
