I fished some gin clear tanks on Oklahoma where I could watch the behavior of the fish with different lures and techniques. It always helps with the attitude to just sit and watch what goes on.
Man, I haven't seen the word tank used since I was in the Air Force in the 70's! I fish local ones near Wichita Falls and just over the border in OK. as much as I could!
Course, I didn't have a boat then, having to live with family off base in an apt., but did fish with an officer who was as avid an angler as me who owned a boat.
Man do I miss those days and Texans in general not to mention the 3 tornadoes I witnessed that were mesmerizing to say the least (but only so long as they continued north away from me!)
