It seems that there are many locations that have been in the GTA V trailers that still haven't been discovered by a lot of people. Well, worry no more, because this the thread for you!
The point of this thread is to point out locations that you may or may not have come across yet, nor know where to find it. For example, I, and probably many others, have not discovered this location yet.
Now, this is what you can do to help: Simply take a picture on Snapmatic of the exact location, and post it here, along with a screenshot from the trailer that it's in for reference. Then, if you want to really help out, post a picture of the spot that it's in on the map.
I will try to post some of tomorrow, as I have been able to find a couple of locations already. The first one I found was actually the scene where Franklin is in the red car, revving up the engine while the girl crosses the street. Looks even better than in the trailer!
Let's get this party started.
