@Bradley - I didn't tag them originally and don't particularly care how
they're tagged. Routing in rural Alaska is pretty simple because there's
only one way to get from Anchorage to Fairbanks and to Homer, where I live
LOL. That's why I prefaced my comment by saying I have no stake in the
outcome of this conversation. I only want to stay tuned in so I can
understand any changes to our rationale.
