Portland in the winter. Basically, it's gray. Dark gray and wet. Now, the awesome thing is that a) green looks really good when it's gray out and the whole place is covered in green. b) you can get on your galoshes and remember reading the stories of Ramona Quimby and Henry Huggins and their rainy day Portland adventures and make your own footprints in the mud.
Which is exactly what we did when we went down to St. John's on a very muddy day and checked out Cathedral Bridge and the ducks and seagulls that were hanging out in large numbers.
Interestingly, unlike Iowa where ducks reign supreme, geese are the most prevalent. Sooo, it was nice to see some ducks while visiting, what some call, the "mid western" area of Portland (aka St. John's).
Have a great day!
