My father's last trip with me was on the White for big brown. I cannot remember the guide's name, but he was a police officer near Gassville. Elvin? Molting crawdad specialist, We caught four fish - 5 to 9+ pounds. We turned them all loose. At the end of the day, dad said, "Brother (his nickname for me) that was great, but these boats and seats hurt my knees." I never got him out with me again, but he was nearly 80 at that point.
Take the "dad" out as often as you can, take pictures.
