Most places above a certain point in this country will experience at least one snow day during the winter. Where I grew up, we would be lucky if we only saw five or six. Often we would be in school for an extra half month due to the snow preventing the buses from running in our area. Although most work places won't close down as easily as schools do, every now and then you will get those storms which shut almost everything down. Those are the days that most kids dream about but most adults dread.
If you have an apartment building or complex, you may be able to help the adults reconnect to their childhoods and enjoy their snow day just as much as the kids do. If you have a snow removal protocol that allows for people to stay on the property, then it is always a good idea to have a few activities planned in a common area so that either the kids in the complex can be taken care of while the adults move their cars or where everyone can have a good time while the snow continues to fall.
A crowd favorite is always going to be hot chocolate and marshmallows. Getting these things doesn't have to be expensive and now you can even get hot chocolate with the marshmallows already included. Having a projector screen and a family friendly holiday movie such as The Polar Express or Santa Claus is Coming to Town is also a great idea. This will keep the children occupied and give everyone some time off of worrying about what they can do while snowed in. After all, isn't this starting to sound like a pretty good idea to do by yourself for a day or two?
The great thing about this is it doesn't even have to be during an actual snow day. If you want, you can plan this to happen one of the weekends of this month as a community event. Having a place where everyone can get together and have a good time is always something that can be appreciated by your residents. It certainly doesn't hurt to save the idea for a rainy, or snowy, day though.
