the map is going to be freakin huge! its not gonna be a short walk at all, if you do walk it will take around an hour or more to walk straight through, think how long it will be to walk a road all the way back.
since the whole world is open, im gonna check and see if the drive thru works at fast food places, then i will go find a truck (not semi) and drive all the way to the beach, rent a mini submarine and explore the ocean and see if i can kill a shark, and when im done with that i guess ill parasail and problably crash a plane into the ocean and to finish off messin around i will go to a bar, get drunk and drive a sports car while starting a poice chase to an air field! =) you can say rediculous all you want but i have always wanted to try drunk flying
