Opening day here in PA is usually the first weekend of Oct....I've successfully grunted in bucks the first day right thru to the last day. The key early season is not to be aggressive......usually I never grunt unless I've made eye contact of a buck...then I'll talk to him if I know he's not going to pass within bow range.

Scents on the other hand are a waste of money in my opinion.....yes they can work but not enough to warrant the costs.
