That’s a whole lot of walking. Wow! We probably did almost as much on our trip but we were a few years younger. There was four of us - My hubby and myself and our best friends. That kind of walking sadly isn’t in our future any longer. Hubby recuperating from total knee replaced and we both of arthritis in our backs. Getting old isn’t fun for sure. But I’m glad we did the things we did when we could. My niece and great niece were just up in NYC a couple of weeks ago and walked all over and said they never saw anything bad. They did avoid the subway. They were scouting out living arrangements ( a big yikes) as my great niece starts her job with a large law firm up there in October.). Should be interesting. She comes from having lived in a 5000 square foot house with her folks. Graduating from Richmond Law School in May. I appreciate your info and thank you kindly.
