Seattle dogsled

I had a dream the other night - suitably weird, with many things that I don't remember, but this one I do. 

I was out in the drive and saw someone/something approaching. I had an expectation of who it might be, but it was not them. It was Roy, and the whole family, on a wheeled dogsled pulled by a single dog. I was not expecting them, or expecting this form of conveyance. 

They all debarked (if it's not a word it should be), as if all was perfectly normal. Twelve hours it took them to journey from Seattle to Trout Lake. I wanted to know the route they had taken, but before I found out other suitable weird things came to take my attention.
