I'm sure the data is out there somewhere, but looking at the NDIC GIS map, the 7.5 sections would most likely be:
- sections 25 - 27/T153N-R101W
- sections 34 - 36/T153N-R101W
- section 6-T154N-R100W
- and section E2 of 1-T154N-R101W
Highway "2&85" pretty much runs up the middle of these sections, with commercial activity already in place along the highway.
