I can see it now-suggest you clear cache/recent history of the browser you are using and try again, if that fails, try a restart.
It was extensive discussed at thaivisa forum, but if I recall right, no one brought an evidence. That the tiger are very tame of course let someone think
No one, including animal rights advocates, working at the facility, has ever witnessed drugging of the tigers.
Well this North/South/East/West can be very confusing.....
Can you try a different browser?
I used Firefox
