What are you going to do once the undead rise?

[Rock Monster]

...Besides what happens if someday down the road you guys exhaust all your supplies and there is no gas to fly the planes anymore.

You know what we do on our island we take a ferry 40 mins to land and get more supplies.

a) we use either the heli-chopters, subs, cargo ships, aircraft carriers, or yachts that are already there.
b) we fly/sail/etc to the main land to get extra supplies before we run out
c)if you run out on your island, you would be in the same situation. it's a moot point.
