We like to hold the Winter Work Weekend on President's Day weekend, because it's a long weekend for many. This year the calendar puts it on Feb 21-23, but that's incorrect because this year's President's weekend is Feb 14-16. So the WWW is being declared for next weekend, Feb 14-16.
That said, the only project of any consequence that can go the whole weekend is Locomotive 9. Jason will be there to run things on Saturday and Monday, but cannot be there on Sunday. We cannot cut trees because there's 3+ feet of snow on the ground. We cannot work on the car barn for the same reason. There's #9 - or there's shoveling snow. Which would you rather work on?
