Grand Cay is in the North East quad of the Abacos. NNW of Great Sale, and the Next Cay South East of Walkers. In fact many of the locals there used to work at Walkers while it was in its day. Looks like a good stop to use as a base for dinking.
Last week we paid 6.13 for diesel using a card at Lighthouse, and 16 something for 2.6 gallons of gas in the dink.
