I have to ask. When would anyone be able to wear a bikini in Alaska?
Well, when I got up to Alaska, I didn’t see the sign, but I was told by some fellow pilots (way’back when) that there was a sign put up at an Eielson AFB swimming hole “Swimming forbidden if air temperature is below 10 degrees” or some such.
After being in -50 for quite a while, that feels very hot, and people will want to cool off.
They have summers.
