I have had the excellect good fortune to go elk hunting in Idaho several times with Mike Westvang. Mike grew up hunting elk in the Northwest.
When tring to cut off elk, we would "dive" into and thru some very thick brush (bushes) that were 7 or 8 feet tall and thick as a hedge row. I don't see how you could get thru them with anything but a side quiver. That is what Mike and Jason used. I followed their lead and was glad I did.
The other good thing about a side quiver was you could carry 2 or 3 grouse arrows
. Elk hunting can often break out into a grouse hunt.
If you have to hot foot it thru the huckleberries, avalanache bush, etc, it will test your arrow carry system to the max. It is gonna be real easy to leave some arrows in the bushes if you can't keep good control of your quiver
