It's not practical to hunt them together. You can hunt half the hunt for one, and the other half for the other.

Next year I plan on hunting bear and elk together, but the bear hunt is a month long in Sept, and the elk hunt is right in the middle of the month. When i'm hunting elk, I won't really be hunting for bear. Unless I get an elk, and then i'll be keeping my eye on the gut pile for bear.

Deer will be in Oct. I would never hunt deer and elk together.
