Franklins trailer, hes talking with his back to a wall covered in graffiti and near the bottom it says grove. Could be a reference to the old grove st, or grove st could exist? Could explain the green vs. Purple gang colors.
The games looking great and they werent kidding about it being huge. I am looking forward to trevor the most but its a pretty tough choice, they all look interesting. Cant wait to explore again like i did in san andreas.
