RE: Early Goose?
You might be thinking of some of the Westmoreland County Parks that open on certain days for early goose season hunting. They are managed differently from state parks. I think in the past Northmoreland, Twin Lakes & Mammoth Parks have all had this opportunity, but you usually have to hunt on a weekday and only certain times. Not sure what the deal is for state parks, but I would assume that the areas that are usually open to hunting on Lake Arthur don't have separate regulations for goose season. They may however open certain parts of the park to goose hunting that are not usually open to any hunting, kind of like the deal with the county parks in Westmoreland that do this, although I've never heard that they do this. Only a guess.
