I know a guy that twice sent pictures of a mature buck swimming across Lake Texoma within the previous 3 weeks. One time he plotted the bucks path and said he was over a mile from the closest land. That buck was likely swimming 2 miles to get some strange. What if these bucks had bad genetics? Keeping bucks with bad genetics from your doe herd isn't as easy as choosing who your teenage daughter dates.
Buck on Kaw lake. He has already swam a mile, and has 3/4 miles to go.
