Since antlers are the only trophy part of a deer, elk, or moose, why not just buy meat at the store and avoid cows and does all together?

You can buy quite a bit of meat for the price of a Colorado cow elk tag and a lot more if you factor in the ancillary costs associated with hunting.

The only reason that I shoot does is that I can do it with an almost unlimited number of inexpensive "River WMA" tags here in Nebraska and even when I do shoot does, I typically give more than half the meat away via Hunters Helping the Hungry.
