Generally until someone refuses to leave when verbally asked a trespassing charge will not result. However, a general no trespassing sign can bring the charge right away. It gets very sticky (see my previous post) when you say trespassing for this or that (with the exception of hunting, there is actually a law in Indiana concerning no hunting signs).
The law is not about the sign, the law is you must have permission to hunt on someone else's land.
