There has been an initiative ongoing in AK for many years to upgrade EVERY rural runway to roughly 4,000 feet in length. The idea was to permit operations by larger aircraft, for example fuel tankers. Many of the interior villages get their heating oil (and pampers and beer) in airplanes like DC-4/6, etc. That initiative is almost complete. Almost every village (like tiny Birch Creek, population of about 60) now has a 4000 foot runway.
The challenges that Alaska commercial aviators face are generally the ENROUTE portion of the flight (and/or FINDING the dang runway). Also, while there are a few pretty tough air strips in the lower 48, no doubt, there is very little real off airport operation down here, and LOTS of that in AK, even by 135 folks.
Finally, even a 4000 foot by 100 foot strip may not be very friendly in a 30 knot crosswind and a mile vis with low ceilings. ANd, that's the kind of weather those folks fly in....regularly.
Flying is simply different wherever you go. When I moved off the AK Peninsula to Kodiak, I thought Kodiak was great, cause it wasn't very windy. Compared to CDB, that is. I moved to the interior, and missed the coast, where I could fly at 200 feet and hug the coast in lousy vis, and know where I was all the time.
Every place offers it's challenges. In Alaska--it's the weather in one form or another that will make you earn your pay most days.
