I really wish I could have a safehouse out there outside of Trevor's trailer. It has such a lawless and off the grid kind of vibe to it that to me it makes it a perfect place to do police chases and shootouts. I also love how you can be driving around and all of a sudden you come across a police shootout and if you help the criminals they let you have some of the money.
After the beach area by Del Pero and Vespucci it is my favorite place on the map. It's like no mans land out there and it feels dangerous.
