You're gonna have a BLAST!

The downside is, you may be spoiled for hunting anything else.

First, get is shape. Second, get in BETTER shape! Third, learn how and when to call. Fourth, get some good, lightweight boots (Break them in!)

Since you're going after cows, take a look at ElkNut's
Bugling Big & Beyond Vol. 3, "Calling All Cows". The rest of his series is excellent as well. I always recommend the Primos "
Mastering the Art Guide to Calling Elk" as good introductory material.
HuntFlix currently has nearly 600 titles in our library, with
46 titles just on elk, so there is plenty of material available. Our rental program makes it possible for you to watch dozens of different titles without spending a whole lot of dough, and when you find a gem that is worth adding to your permenant collection, we can help you out there as well.
Wouldn't it just blow your buddies away if you showed up in elk camp and could out call them?
