Will back into the driveway if I know snow is incoming. I think it is easier to get out of the driveway and ensures i don't have to stop to change directions when backing out. I will back in if the parking lot is tight(at work). Otherwise, I typicaly pull in and back out. I feel there is less chance of backing into the cars on either side if I back out as opposed to backing in. I will always pull through if at all possible.
