The Elkhorn has plenty of kitties, Prairie View which is darn near in your backyard has plenty of fish to keep your kids busy. It is located just west of Bennington Lake(the one with all of the enormous houses on it on hwy 36). Lake cunningham is located at about 90th and hwy 36, was recently renevated and has lots of fish, probably on the smaller side. The walleyes are just nearing the 16-18″ range.
That should be enough to get you started close to home.
I don’t live far from you, so if you need a hand controlling your deer population, just get in touch with me. Way too many in that area.
