Check out Varmint Al for lots of good info.
I found a website by Varmint Al. Lots of good info on coyote hunting. Not sure how much applies to wolf hunting, but it's worth checking out.
There is a lot of talk on here about the wolves killing dogs and the worry of an attack on a child. VA also has a section on coyote attacks on dogs and children. If coyotes will attack a kid, I don't see why a wolf wouldn't try it. Sure hope everyone gets to keep their socks though.
I built VA's electronic caller using my son's ipod. Works really well. I have only got to get out a few times, so no luck yet, but hopeful.
