Of course, in a snow emergency, trucks can't get stocks to the stores, so there's not much point in going to the store no matter how you might be able to get there ...

It really just underscores the importance of having a good supply of non-perishable food and clean water laid up, rotating your stocks regularly, and having a disaster plan ... it's been hard lately since we just don't eat that cr*p any more, so our emergency food stores tend to get stale and get thrown out.
