Probably 'possums. Vaguely similar colouring (just not the tail and mask) and in the area (I see them dead along a lot of roads -- especially Sammamish Parkway)

TTFN - Kent

I checked again with her. Fat, spectacular, ring tails, animals the size of hogs. Maybe they were sasquatch babies. :)

Come on, of course there are racoons in Redmond, Brian! I don't think I've seen any that were pig sized, (I'm not really sure what pig-sized is when it comes to racoons) but I've certainly seen them both skulking about and (I'm very sad to say), on the road... You know, I had a friend who lived in wallingford who had what she called giant racoons take over her place while they were gone for a week. Maybe they are the same ones!
