Flying in Alaska, precautionary landings are quite common (or at least for me). The memorable ones are when you get stuck for a day or more. Here is a "rest stop" last week, going from Dease Lake to Smithers, BC. The great thing about a road, is sometimes you can get info from passing cars as to whether conditions are improving.
Here is a photo of about a six hour weather delay in SW Alaska, an hour before a brown bear cruised down the salmon stream past us.
