First of all happy new year. Having flown around for a bit both in sim and in real life, I discovered something. I was going to San Francisco on the 27th and it was rainy and the red lights were not on, but the yellow flashing lights are on all the time. A question though, later last year, Vancouver swapped the takeoff and landing runways around for some reason, never found out why. There wasn't runway maintenance in progress, so why did they do that?
