I bought Elknuts video/cd #1 earlier this year and have been practicing. I had a hoochie mama call, but after watching/listening to elknut, I bought a diaphram call and it's made a huge difference. Since I will be hunting 2nd season here in CO, I've only been practicing my social/locator cow calls. As skeeter suggests, I keep the call in the truck and practice to and from work. It's a 1/2 commute for me, so I get in a good amount of practice. Hopefully it all pays off. Good luck to you!
