The same type of guys that will go to the driving range to "golf", but refuse to walk 9 holes let alone 18. Too much work to get to the alpine when you can just wait for the snow to push them down. I guess to all their own.
That's when the lazy people pick up their rifles. August/September alpine hunting is probably my favorite type of hunting. Calling them in in the rut in the fall/winter is awesome too; but nothing beats glassing for bucks on the high ridge!
Beach cruising is okay for shooting meat deer, but I don't think bucks shot off the beach are as 'deserved' as ones you hike muskegs and call in; or climb mountains to harvest. A big buck that has outsmarted every hunter all year long, only to be pushed to the beach to eat seaweed out of starvation in the dead of winter and gets shot; is hardly something to brag about.
Personally I think October is prime time for deer hunting in the Sound.
They are spread out across the range fattening up before the rut. It is cool enough to be comfortable and knock down the bugs but not cold enough to require heavy clothing. The leaves are falling and annuals are dying off so visibility is good. The length of the days allow for an honest day of hunting and a decent night's sleep. Toward the end of the month you might get a dusting of good tracking snow but never enough to push them down.
