Fun! Also created a spatial and non-spatial approach. I didn't know you could customize the Find Nearest tool to whatever number you need.
Tackled this in a cheap-and-cheerful kinda way. going to look at other folks' solutions next
This was a fun exercise! Don't get to use the spatial tools that often. It would have also helped if I would have read the instructions and realized the distance measure was meters and not miles like my brain interpreted from "m."
