Stik,
I remember posting on the Barbados scene just after I got back about 2 years ago, I beleive it hasn't changed much since then. The thread was quite lengthy and I remember seeing it in a search of the caribean forum a few weeks ago.
I really enjoyed myself out there, Barbados takes about .8 tacho hour to get around, and after that there are endless island hopping opportunities. I beleive the airport has undergone some rebuild since I was out, but I don't think its changed much in terms of GA.
The GA scene is small out there, one flying school with a few aircraft, and unfortunately no Pitts :-(
If you want to know anything specific drop me a line and I'll do my best to answer. I also know the "most reputable tourist information" guy out there who really is top noch and publishes most of the books about the island, so if you want to know anything about general Barbados life, I should be able to answer those queries, if not I can put you in touch with the guy who will.
Have a good time ya lucky sod!
Rusty.
