Texans!  Is the Lake Texoma Bigfoot a thing?!?

This was on the Travel Channel, which, as I have mentioned here before, should now be called the Bigfoot Channel.

This episode had a dramatization of brothers who had an encounter with some kind of beast. They think maybe it was a Bigfoot. Is this a popular urban legend around that area of Texas? Or, a rural legend, I guess... I'll just call it a legend. You see where I'm going with this. Do people often claim to have strange encounters around there?
