That makes for over 30 transit hours and 5556 miles in one week. Wow. I changed the flight so I could take Saturday to check out St. Lucia - on my own time/$, since I imagine the remainder will be somewhat reminiscent of the GEO Juvenil Mexico meeting, in terms of not seeing much aside from work spaces, sleep spaces (http://www.glencastleresort.net) and food spaces :)

Anyways, things are starting to come together, at least from my end... Got the presentations looking decent and starting to get my confidence up - despite the fact that I just spoke to Osmond in Barbados and he emphasized how important my (UNEP's) comments at the press conference would be... EEK - Wish me luck!!
