Here, there are actually quite a few paved runways. Obviously the cozy could not operate out of the gravel or roadbase type runways, but even the nearby village of Galena, pop 700ish has a paved airport as it is a regional hub. But mainly I was thinking of airborne conditions. Flying in -45 degree weather (but always keeping an eye on icing conditions) and dealing with high turbulance/heavy rain.
Perhaps some folks have rough weather stories that would shed some light?
