More often than not, farmers are happy to have responsible hunters attempt to remove some of the geese that do so much damage to crops throughout the year. Large decoy spreads, good calling and concealment are all necessary to fool these wary birds, which have already been hunted off and on since Labor Day. Particularly productive areas are the western edges of Montour and Northumberland counties. For those who prefer public land, the best bet is to stick to the series of large islands that line the river between Sunbury and Harrisburg. A couple of good ones are Hoover and Sweigart's islands, which are also known as State Game Lands 233 and 258, respectively.
