Its fake (from someone who obviously doesn’t have a map either).
Might be fake, but there’s nothing stopping a private individual from doing this. Free speech, etc.
A billboard costs what, a couple thousand bucks for a few weeks? Somebody out there can afford it.
Might be worth it just to see the reaction in LA.
The intended audience is in L.A.. Were it for the illegals it would be in Spanish. However, if they took a left on I-8 it would take them back to Mexico. That part is good.
I agree with your assessment - the billboard does not exist.
