Birdgugker wouldn't know a Mexican from a Romanian.
I dunno, I seen a bunch of Romanians five years back when I rode around the UK, almost as many as I did Polish. Both places are members of the EU hence their free ingress to the UK. Very nearly got run over by a Polish guy driving a milk tanker truck. Neither one looked like Mexicans.
Mexican/Honduran/El Salvadoran/Guatemalan are tougher, especially if ya don’t habla Espanol ( I assume they all have their own accents). They seem to run shorter and more bow legged as you head South.
