I usually just pick a direction and go, but I'm going to plan a trip for once. I live in Plymouth county Iowa (NW corner) and am looking for about 6-12 hours of riding one way to get somewhere, then two days riding around that area, then head back. Obviously I could do the Black Hills in western South Dakota, but what else is there within that 6-12 hour ride time from here? (6-12 hours at roughly the speed limit mind you. I'm not going for any records or a gumball run here.) I would prefer to stay away from the cities as I hate large crowds of people and those abominable eyesores people refer to as skyscrapers.
