Yes, Sandy is certainly annoying.

And every time they showed her, I kept thinking "She's wearing dentures; I certainly hope they give her denture cleaning stuff/adhesive!" I know they don't give the survivors toothpaste/brushes, but what about denture cream? Can't you just see her dentures flying out during a challenge? (I apologize if those were her real teeth

)
I think it was interesting how Sandy and Sierra chose to do different things with all their "free" time since they got to camp ahead of everyone. I could see Sandy's point - it was kind of obvious they were going to vote her out, why not spend the time looking for the idol. But she should have done
something around the camp, building a fire pit or something. Sierra isn't going to last long if she's really that sick - strep throat, 102 temp.
I, too, like the army guy - if he's been in Afghanistan, he's used to heat and lousy living conditions, so he should do pretty well. Then again, wasn't he an officer and used to ordering people around? That might get him into trouble.
