Huntersun, a bit more infor would be helpful.
What state do you intend to hunt in?? How many days do you intend to hunt? How many hunters in your party??
Have you elk hunted in a western state before??
That said, there is a magazine called "Bugle," published by the Rocky Mtn. Elk Foundation, which has a lot of ads in it by various outfitters in the elk states. Some of them take hunters in on drop camps, and they usually list if the do.
Frankly, if this is your first hunt for elk, I suggest you spring for the fully guided hunt by a reputable outfitter. You can spend a lot of money just being "dropped" and you might not be in a good area. You certainly won't know the area and a good outfitter will, plus he keeps up with the movement of elk during the summer and fall, so he can put his dudes on them during season.
I live in elk country, and spend a fair amount of time scouting for them... and it still ain't easy.
Just my opinion. J,B,
