Hang in there Scott. Pretty soon you'll have a couple extra astronomers out there with you 🙂
Rebecca, Dean's is really easy to find. We'll probably meet there (?)
South on 52, 52 turns into 44. Follow 44 until in Spring Grove. Drive nearly straight through until 2nd St SE, take a right. 4th house on the right.
To get to the farm, take 16 south. Right after crossing the Iowa border, take another right into the driveway of the farm. Dean will have to give us a landmark to know for sure which driveway.
