I like reading behind the scenes things on here especially on past challenges so I thought it could be a thread on it. Somethings I know... 1. Piggy from Road Rules Australia was originally casted on The Inferno and can even been seen in footage and photos when the cast arrived. She left as soon as she arrived and Christena from Road Rules South Pacific replaced her. 2. The Gauntlet 1 was originally suppose to be in taped in Rhode Island before Telluride, Colorado. 3. As of Duel 2, Beth, Derrick, Katie, Robin, Tonya & Veronica have all done the most challenges with 7.
