Sorry for the delay - I spent an hour or two making a spreadsheet including ALL the countries that won medals, only to find that there was no easy way to display it here! The table of countries that were actually picked by commenters is below. If I've navigated my way through Google Documents properly, you should be able to see the whole spreadsheet here. The Bahamas were the overall winners - although none of us picked them.
There was no tie, so no need for me to try and figure out how to convert your medal predictions to standings - phew!
Mermaid can has bragging rights and a gold medal! Nice job! EcoGeoFemme takes the silver, and Kristi takes the bronze.
Thanks for playing everyone - this was fun!
How long till the Paralympics?
