RE: Calls???
I'm in SE Nebraska and I'm gonna start using them next weekend which is the first chance I'll have to get out. The Rut will be right around the corner and the bucks should be sparring for and hunting does from what I have read. You might have some luck with light rattling this weekend.
There's another post on here that talks about rattling and someone posted a link to an Iowa buck hunting article about the 5 different phases of the hunting season and how to rattle for each. It was a very informative article. Do a search for rattle or rattling and it should come up for you.
