As everyone else is saying, I'd bet dollars to donuts that these are Gypsies and not ethnic Romanians.
And you're absolutely right about most Third World immigrants being perfectly happy to wallow in their own filth - whether it's Gypsies or Somalis relieving themselves in the street or Mexicans throwing their kids' soiled pampers into their yards, even when offered basic sanitation in America or Europe.
There are pictures of them on the link. They don’t look like Solials but yea look like Gypsies.
Or on the beach. But then, it wasn't only Hispanics I saw do that on the beaches in California.
On a guided trip down South I once witnessed Ed Gillet tell the owner of the, um, camping spot, at La Bufadora that somebody should write a song about her pricey "toilet" facility. Ed Warned us not to use it. Got Hepatitis?
Quite a contrast between the sanitation codes in TJ and San Diego.
