THEME
Well, it looks like The Amazing Race 5 is still shooting and has made a stop in Canada. According to the Calgary Sun, the racers had a challenge - either a Roadblock or Detour - at Bow Falls near the Fairmont Banff Springs Hotel.

Also, in something of a shock if you follow the show, casting is now active for The Amazing Race 6, which is due to shoot in August. Applications are due April 13.

Another article also mentions that CBS will couple Big Brother and the Amazing Race to create a two-hour reality block on Tuesdays from 9-11 (8-10 Central). Both shows will have 90-minute season premieres on Tuesday, July 6, and will remain on Tuesdays. (Big Brother 5 will be Tuesday nights 9-10pm ET, Thursdays 8-9pm (evictions live in the eastern timezone), and Saturdays 9-10pm ET.)

In still another twist and tie-in, Big Brother 4 Runner-up Alison Irwin and her boyfriend Donny are one of the teams on Amazing Race 5.

There is a report that The Amazing Race may have two new twists (other than Alison):

During non-elimination weeks, the team that finishes last will be stripped of all their money -- and not be given any coin at the start of the next leg of the race.

There'll also be a new "yield" component to the game that will let each team slow down someone who's lagging behind them in the race. The "yield" can only be used once by each team.
