Bretto,
I used to own a business and worked as a sales rep in the Manhattan area, and I took more than a few classes at KSU before I went to KU for med school. I lived there for bout 8 years so I used to be pretty familiar with the area.
I used to live a mile from the boat ramp to the blue and hauled a lot of big cats out of there. I would like to fish that river again some day but its only a pipe dream. I live close to the Des Moines River and it seems like a giant untapped resource for big cats cause nobody fishes for them here. I have been here over 15 years and haven't taken the time to get down there yet. It's something on my need to do short list. I used to get down to the mouth of the blue where it dumps into the Kaw but I had a lot of good holes upriver from the boat ramp that I preferred to hit. Good luck with your lines on the Kaw.
