Check out SKYBUS.COM. They have non-stop tickets to Fort Lauderdale from GREENSBORO from $10 one-way and up. What you save on the flight will help out on other expenses. Lotsa dive shops there or you can go further south. I fly them every month, round-trip, for $40.80 from Col's, Ohio. I rent a cheap car from Payless or whoever is cheapest that month and make it down to Largo or Islamorada in 1 1/2 to 2 hours. You can get three days of two-tank dives for around $170 plus tax in a lot of the shops in the upper keys. I like Key Dives in Islamorada because they furnish a DM for every six divers at no extra cost, eliminating navigation worries and if you need any equipment they are very reasonable. Best dive shop in the upper Keys as far as I am concerned.
