Where are the xxx scenes filmed?

[bernis]

Hi everyone,

I've always been curious.
Most of the scenes on websites like bangbros.com, vixen.com, brazzers.com, rk.com, evilangel, etc.

are filmed in what cities?, or at least what states?

Is it nationwide?

Just out of curiosity, does anyone know?

example HARDX.COM  It's a Canadian website (that's what Google says). Are their scenes also filmed in Canada?

Best regards.
