I dont know of any sites but i do a huge amount o goose bustin here in central VA, and early season w had great luck everymorning in corn fields. The past few months however birds are not landing in crop but in psture and big water. This week is the first week i have seen a lot of birds in a few of ny good holes since about a month ago so i think we are gonna hit them hard this thursday and get it while its good. Many migrators are just getting here!
