1 ) I would get to the singles bar. Since Zombies can't swim, they could not reach me because the entrance is in the water. ;) I could stock up on red juice >:3
2) TO THE GROTTO!!! Farm for life with those 10g bombs and stock up on arrows, afk in the water and chill on the tables.
Those pesky zombies would have to gain 2000 hours which would give me a lot of time to plan for backups! >:3
3) The bridge near the entrance to York town! Its a complete swim area and you could stand on the rocks if you squeeze between them :3
