I think its the season 6 finale today. They are showing seasons 3-13 one more time. We will probably see season 14 and 15 in 2010.
Just got an e-mail from TNS Gallup the company that gives us the ratings. Since August 1 The Amazing Race has had an average of 27.000 viewers, that is a 3,1 % market share (?). But it hasn`t had any promotion at all so I`m not surprised by the low numbers.
