I feel for the Rockers, but honestly this is the ONE thing you should always keep on you. I know many people don't like the twins or team University of Texas (they do not represent all Texans, and these two are attending UT), but there are ways to work around the money issue on rides (that are legal in the contest, as you are not penalized if the driver chooses to give you a free ride), but they didn't forget this basic concept.
Given I've recently lost my Dad, I look at this and think to begin with "why didn't the team consider dropping out?" The reason I say this is because a. their minds and hearts weren't quite into the race post this announcement and b. they lost some precious time with the one member's dad. It's probably why I've NEVER - even before recently, faulted Jenna Morasca from dropping out of "Survivor" when she felt something was wrong with her mom.
