Rob has since gone out with the shovel and reduced them a bit.
The other surprise is that we had sun coming into the house this past weekend!!
Of course, winter sun can sometimes be associated with clear cold nights. We didn't go far on Saturday what with -50 F at the airport and dense ice fog in town. Then we went to town on Sunday and no one came to our class - even though we had to go. We almost hit a moose coming home after dark.
