I am nearly snowed in at the moment, would be if I didn't have a 4x4 to rely on.
In my case it is whether I can get safely down the hill to the main road that is always the first question. It's OK to get out if I have the car parked at the bottom but I don't want to carry the instruments a mile on foot, which is where our un-adopted road meets the gritted surfaces. The hill is about 1 in 6 at its steepest and often has ice refrozen from melted snow across it at irregular intervals when you come back at night.
I have once had to do a controlled reverse slide back to a section with more grip and fit chains to a Freelander in the middle of the night!
It you are fit this sort of goings on is just more exercise but when you have to consider the odd twinges from a delicate back you think twice.
The second thing is are the roads you need to travel on open at the moment and are they likely to remain so?
Do you rely on satnav or do you have a good map with you to work out alternative routes?
Have you got a spade, water, flask of hot drink etc.?

Will you have an audience or will they have cried off too?

Best of luck
