I just had to add a coda. Our last trip on the underground. London underground and transit system is amazing. Dennis looked it up. 5 MILLION a day use the system. This picture really doesn't adequately show the morning commute crowds. Even with all the people you are on your train or tube within 5 minutes. Breakfast at our hotel, the underground and now at Heathrow. I was feeling pretty anxious about getting here and navigating Heathrow. But all went well. Dennis just has to put up with us being here early. 😘
