Those lumps in the snow are deer! There are four (the possible fifth is actually a stump), but I think it was Christmas Day when we saw six and actually watched them bed down. I've always known that there were deer in the 'hood and I've even seen them before, but I've never seen them like this. That there are far fewer dogs around here, at the moment, especially loose ones, is one likely reason.
I had a Skype chat with Maddy -- safe in London -- yesterday and she's doing fine!!
