 Ben Westfall helps Brian create homes for Purple Martins here. The two have lots of birds that annually call their respective places home. All together, I have 600 plus in two locations. Here in Griggsville, you'll find a giant tower of Purple Martin houses. It's a symbol for which the town is known. J.O. Wade put the tower up and framed this as the Purple Martin capital of the nation. But then he went to other states and other towns. He helped them to become their Purple Martin capital of the nation.
