I got very confused when I was arriving back at a small US field with two runways in use and where the wind was quite brisk & moving around quite a bit.
After listening on the unicom, it seemed that 27 was primarily in use but I did hear reference to someone on 20. As instructed by the FBO beforehand, all arrivals are on a 45 into the pattern and so I entered on a 45 LH for 27. As I did do, I stared down at the guy on 20.
No one was fussed and it all seemed pretty normal but still not sure if I was wrong or not. In hindsight, I should have just joined on base but no one seeme to do that there.
OK, so not an overhead story but one that go my heart racing.
