Plymouth Massachusetts 400th year celebration parade is on this year! It was really 400 years last year 2020 when the Pilgrims sat down together with the Native Americans and celebrated their first year. Covid postponed it but it is on this year November 19th to 21. The parade will be on Saturday November 20th. I have been to this one, one of the best Thanksgiving parades in the country. And besides the parade, the town of Plymouth is full of history. Lots of activities for all ages.
