Iowa, South Waren County, We used to successfully morel hunt around Sailorville lake west of Polk City. Generally around the bike trail. Since we don't live there anymore I am giving it away. Point Google Earth to 41deg46'01.27" N and 93deg44'59.08" W. That is about the center of the area. We also used to find bunch of whites just behind houses on southwest side of the town.
I would like to add to wear long pants and long sleeves to limit ticks as much as possible. This is the worst tick year I remember.
