There’s a beach called Los Tubos in Puerto Rico (http://www.beached.com/beach/puerto-rico/coto-norte/9723), but as far as I know, Villa Los Kubos is a fictional area in PR. I’ve never seen any reference made to a specific town or municipality in Yenny.
There’s no way to know, but I would think Fajardo (http://welcome.topuertorico.org/city/fajardo.shtml) is a likely candidate.
The earliest I can remember using was Windows 3.1 at school. I don’t remember the make of the first computer we had, but it ran with Windows 95. I’ve used or had all the Window OS since then.
Feliz Cumpleaños, Yenny!!!
Love the hair-do today.
