Sounds good, to a point. That is a prime location, as described. However, in my personal experience, you will not call him "up hill". He will come DOWN to a call, but it is very difficult for you to sit up on top and expect a cat to approach your stand. Call, and target that hill, if you like, but do it from somewhere along the base; whatever looks good. I don't know the reasons for it, but that's what I think.
Good hunting. LB
