Found a couple of roadside signs etc.
This one is at the entrance to The Lost MC hangout at Stab City.
I spent hours searching but could only find two images on the internet. Both of them only show the upper section, but you can just see the top of the arrow in one of them.
Neither of them had an address for the sign, so I have no idea where it's located or even if it still exists.
Finally found where it is. Now there are hundreds of images on the net.
It's real life address is; Strip 91 Motel, 2091 Las Vegas Blvd Nth, Nth Las Vegas, NV 89030.
Maybe I'll keep looking for the others. Just gotta be patient & hope to stumble across an image somewhere.
Here's a side by side of the full sign.
The "Drink Blarney's Beer" water tank is a direct copy of the Frostop Root Beer mug.
There are numerous versions of the Frostop mug, but the one in Chrisman Illinois is one of the closest matches.
Frostop is no longer franchised, so a lot of the original mugs now have different company names on them.
There used to be a few dozen of them, but I think there are only about 14 left, including a couple of neon versions.
The Yucca Motel cactus sign in Western Sandy Shores has a few close matches, but I don't know if any of them are close enough to call.
There are a couple of real life motels called the Yucca Motel, but their signs don't look like the in-game one either.
Still on the hunt for these signs as well.
There are a few similar looking ones out there, but nothing that could be considered a match.
You would assume that if Rockstar have copied some real life signs for the game, then these ones should have a real life counterpart too, but who knows.
