There are so many threads on this very subject, and some of them are very entertaining!
The bottom line is, you plan ahead and do what you need to do to be at work for your shift. I have had to stay overnight (on a guerney in the Pre-Op area), but almost always am able to get to work and back home again with my Front Wheel Drive Prius. I grew up in Wisconsin and learned early to drive in the snow. On November 1, I pack a bag with three days worth of scrubs
, underwear, toiletries, prescriptions, spare cell phone charger and my travel CPAP. It goes in the car with me whenever snow is possible. You drive slowly and carefully, and allow plenty of extra time. The worst part is probably shoveling your car out after the snowplow has gone by and plowed it in!
When staying overnight is required, it's usually a party atmosphere and I've been slightly disappointed at missing some of those parties! There's one that my colleagues are still talking about three years later. I understand that there was karioke involved. I remember one all-night slumber party during which I got to know some of my long-time colleagues a lot better than I ever had, and it's been much nicer working with them since.
