Yeah, absolutely. If you can get a good line of sight between nodes, the range gets pretty crazy. Altitude is key.

So not a mesh
What you described is point to point
Node to node
Oh, I mean you can get a good few miles between nodes. Then with 4 or 5 in between, your message can go that 100 miles. We have a lot of trees and flat land here, so it probably wouldn't work for me. In a mountainous area, yeah, no problem.
