So far this year our team has held it's meetings, though we did shorten the closing time to noon on the day of the snow-storm (Actually it was a district-wide decision). As for working through snow-storms, I have only one outstanding piece of advice to give. Be careful. If getting to robotics means that you have an epic to recant come the school week, then think of how difficult it would be for EMS services to reach you should anything go awry in the shop. Snow days are good days for media, chairmans, animation, business plan, programming and other non-tool activities.
As for previous years, we we're involved in the snow-storm two years ago and have been snowed in. All said though, the time makes no special demands than any other time; saftey is always the chief concern in our shops.
