At the GZ, you will see a plaque remembering Lawrence Samstad - I for one, appreciate his work here. Feel free to dip your feet in the river while you can.
At the plaque, the reading says ... "Beginning in" and then a year. Consider the date 19AB. Then:
N 44 48.B55
W 093 31.(260+AB)
From here, you can drive or ride a bike to the final.
