SASless,
Absolutely spot on!!! This is why "national" weather minimums make no sense at all, and why "local" minimums should be determined by the pilots with the most experience in the area. And makes the case for NVGs and NVG training very eloquently.
BTW, how much does a remote weather reporting station (ASOS/AWOS) cost? Maybe a case could be made to mount some in the areas you describe even if there's no airport, so that EMS flights don't have to contend with such large gaps in weather reports.
