Mine's not arriving until mid December, so we'll probably have a better idea by then what kind of winter we're in for.
*finger in the air* I don't think you'll need to put winters on until at the earliest late November.
If you have the space and/or don't mind paying for it and for storage, no harm in planning ahead.
pops, how come yours has taken so long? Ignore that, mines going to take roughly the same time actually
