As the son of a person (Pedro Guadalupe Guadalupe, not a mis-print on the name) who IN FACT SOLD THEIR (Mother & Brothers etc.,) FARM (located in Vieques ) TO THE U.S. GOVERNMENT for the Navy to use.

Maybe because quite possibly, your the product of Outcome Based Education. What is Outcome Based Education? Outcome Based Education is Example: Teacher asks little Johnny, how much is 2 (two) plus 2 (two)? Little Johnny answers 27, the Teacher just says your SELF ESTEEM is just so infectious.
Puerto Rico & Vieques in short is the result of the spoils of War.
If you have to ask what War??? The answer is The Spanish American War (1898-1901). See https://en.wikipedia.org/wiki/Spanish%E2%80%93American_War
For others reading this you may also want to read the above wikipedia, reference : 2nd Paragraph, second sentence: American public opinion was agitated by anti-Spanish propaganda led by journalists such as Joseph Pulitzer and William Hearst which used yellow journalism to criticize Spanish administration of Cuba.
Hence, now you really know just what the "Pulitzer Prize" is for. Answer Yellow Journalism. In case the readers didn't know, these guy's (Pulitzer & Hearst) wrote the book on Yellow Journalism.
P.S.
Their's probably a better then 50-50 chance that Vieques community leader Ismael Guadalupe, is some how related to me. I wont be surprised.
