I have spent quite sometime modifying scripts to make a really cool cable car setup. At the moment its runs both ways from the Main Bay in a straight line for about 9 regions.

(Tip) Try using Mouselook for a great view of the islands.

After changing from the Red car to the Blue car to finish the journey there is a Jet Ski at the left side on the dock ready for you to explore all the rest of the Bay.
