I remember a tv show , well documentary on Sky a few years back , where a young man sold everything he owned and raised I think £70,000.
He was then going to Vegas to put the whole lot on Red or Black.
The viewers could select colour and Red was chosen.
This is where things went a bit pear shaped ....it was hard to find a casino that would allow the bet. They did find one, but filming of event was not allowed.
Anyway after the event , they revealed he won bet :-)
