I’ve been away for the last few weeks and missed your post. If there is anyway to reverse your decision do it. Winfly is considered to be the most beautiful time at McMurdo. The air is cold like winter, but the sun is just begining to come up. It’s the time for nacreous clouds and beautiful sunrises. Also the Winfly population is only a third of the summertime. Much nicer. You will also get a headstart on what to expect and will have time to pick things up. It’s much harder at mainbody when the hoards of new people land.
