OK, it is... United States Botanic Garden in Washington, DC.; sorry for the Canadian confusion. I lived in DC for 5 years and loved it. Museums, parks, statues and monuments, people, cherry blossoms, bike paths, no tall buildings, wide streets, interesting architecture, I could go on...
I haven't been there, I am as far from DC as you can get in the states without living in Hawaii or Alaska.
And that it was a few years ago, the clue is a real newspaper instead of an e-reader or tablet. I get my local paper in the electronic edition - leaves me searching for something to put on the table or work bench when I am going to do a messy job.
