Dylan, can't help you at your time, but hope you don't mind me placing my own ad in here. Of course, if for some reason you wind up waiting around until Thursday night, let me know as I am definitely interested.
For anyone arriving to Ft. Lauderdale airport Thursday afternoon/evening (before 8pm), if you're looking to share a ride with two fellow travelers, e-mail me at firstname.lastname@example.org. My name is Andy. I'm interested in talking to ANYONE going from FLL to Big Cypress Thursday evening...if you've got a vehicle already, myself and one other are looking to catch a ride and contribute accordingly. If you don't have something worked out already, let me know, as I'm trying to work out some sort of chauffeur ride for multiple people (must be willing to contribute a little $$).
