Yes! Thank you for posting - I learned a lot that I did not know. My small home city of Holyoke, Massachusetts has a lot of need to know this history - here's a quote from yesterday's local paper:
In Holyoke, the population's Puerto Rican percentage is nearly 50%, which is higher than that of any other city in the United States other than in Puerto Rico (an American commonwealth and unincorporated U.S. territory) itself.
This is a good reminder to me to look to this TPS Network group for resources!
