I took a guided trip on Tenkiller one day, a few years ago, me and my wife, think we caught 3 fish all day. The guide was so embarrassed that he offered a free Trip on Grand to make up for it.
My wife and I pick a day and go to Grand with the Guide, and we caught 2 fish for the days effort! The guide tried his heart out but it just wasn't in the cards!
Did find a really good arrowhead on Grand though.
