Here are some of the photos from that walk. Elfreth's Alley is in the historic area. Some houses are well kept, others need a little TLC.
Montreal has many old buildings that now have external fire escapes. There was a lot of that in Philadelphia, too.
We passed old buildings and newer ones, often in the same block.
I can never resist interesting windows or beautiful ironwork.
Many more photos were taken - too many to upload. It is interesting to see what each of us noticed, how each of us looked and chose to photograph. Flickr friends are now face-to-face friends.
