I'd still be very careful with the GTA Wikia since it's a whole lot of hearsay. But either way, it's a good enough reference.
You got that right, but I indeed compared what we got in Angel Pine, SA and the actual Lone Pine, CA and they are somewhat similar. What's weird is the locations, considering Angel Pine is close to Mnt. Chilliad, close to San Fierro, and Lone Pine is in the middle of nowhere (literally) in the eastern area of California (which is weird).
