You couldn't pay me to do this. I have, what I consider to be, a very healthy distrust of man's ability to control wild predators.
I have the same distrust you do. But I'd still want to go. My wife and I got to pet a 2 year old tiger during our honeymoon in Australia and it was amazing.
I do have 2 problems though.
1. I would like to learn Thai enough to read their "it has been X days since the we've had a tourist attacked" sign.
2. I was unaware there is 2nd reason to visit Thailand and I'm concerned my friends and relatives won't be either.
