Seems like the beginning is Boston and then it changes at some point but I could be wrong
Yes there are a bunch of different cities in there. That's why I started my link at the beginning of the Boston set. I said to go full screen because the pics LOOK SO GOOD but you can go smaller (or hover on the name at the top) for the captions.
