Larry, I did not think there were any deep bodies of water in Iowa. Cement blocks would not help unless you had a deep end. In honesty I have never thrown a gun or wife over board.
I remember a former bowling teammate who tossed his ball into the Cedar River after a particularly bad night. Bag, shoes and all. The Mississippi and the Missouri both have plenty of deep spots, as rivers go. Lakes . . . a lot of ours are man-made. But what Iowans call our great lakes--NW part of the state--there's some pretty deep water. Okoboji is particularly deep, and has darned good fishing. Smallmouths.
Maryland . . . I lived in Virginia for 3 years. I seem to recall there was a strange regulation regarding the Potomac between MD and VA. Most places where a river is the boundary between 2 states, I think they share the fishing rights. Pretty sure I recall that in the case of the Potomac, the boundary was actually the VA shore. If you fished the Potomac from the VA side, you needed both a VA and a MD license . . . although I'm not sure whether the VA DNR guys enforced that. And I suppose, if you put on boots and stepped into the river from the VA side, you would have been OK with just a MD license. Seemed strange to me.
