Forced to trespass unannounced? That's a new one. How are you "forced" to do anything? Did someone pull a gun on you? I'm 50 years old and have hunted all over the world and I've never seen a single situation where I was "forced" to trespass.

Admittedly, I don't hunt many places where property lines are a big deal but I do have the phone numbers of people that own land around where I do hunt. Most the time they already know we are hunting anyways. Personally, I would never set foot an someone's property without contacting them or arranging permission before hand, which is actually pretty easy to do before the season opens. If they weren't there when I called the first time, I'd try again in an hour or so. In this day and age of cell phones, people are pretty easy to get with a call or a text no matter where they are. If I was in a "dead zone" I'd simply drive to where I could get reception.

No sheriff or judge for that matter will buy off on you being "forced" to trespass. Plus, a landowner catching you is well within their rights to get the sheriff to have a serious talk with you.
