Google doesn't have much on "Baht run".
The search function on the website here didn't return much (it doesn't seem to work that well).
I did do a board-wide search on Baht and found some info that I'm still sorting through. For those interested, give that a try. The orig. 750-post thread appears to have been removed from FT.
Here's a link for some info as well...
