I live in Longview right in the middle of hoof rot central. I hunt a lot of different state and private timber company land. I have never seen a elk with hoof rot on state land. Weyerhaeuser land is the worst for hoof root and sierra pacific is a close second. My buddy that lives across the river in Oregon said that they killed a few bulls over there last year that had hoof rot the land was bought by Weyerhaeuser in the last few years. I feel it is something they are using to spray or I would be seeing the herds on stage land with it.
