04-May-2011 -- During a nine hours flight from Frankfurt/Germany to Chicago, I already used my GPS device to check speed and current position of the plane and the distance to the two confluences I wanted to visit in Illinois and Wisconsin.
After landing I picked up my rental car, a nice Ford Mustang and easily found the very close confluence 42N 88W in Elk Grove Village. I stopped the car and looked around a bit to come closer to the confluence but some residents observed me already. Of course, it is always strange, when someone walks around with an unknown device in his hands and takes photos of the houses... Therefore, I decided not to perform the usual confluence dance to get all zeros, although this is the final goal of each visit. I felt I was close enough and didn`t want to discuss with residents what I was doing there. After taking my photos, I entered "my" Mustang and headed towards northwest to 43N 89W and to Madison, Wisconsin.
