Searching around american.gxt and found this unused phone conversation between Tommy and Avery:
Avery Carrington: Hey Tommy, it's Avery! Now listen, I got me all tied up at the moment and I have a representative of mine needs chaperoning out to the Gator Keys. I'm after some land out that way, so I'm sending someone out to sweeten the deal. Could you do me a favor and make sure he gets there ok?
Tommy Vercetti: Yeah, sure thing Avery. Where'd you want me to pick him up?
Avery Carrington: He's just finishing some business at the building site. I said you'd pick him up from there.
Tommy Vercetti: No problem. See you later, Avery.
Avery mentions an area called the Gator Keys. Was this area supposed to be based on the Florida Keys? And where would it be positioned in Vice City?
