Good ol' Dirk Benedict!! Yep, that's right - I am showing my age!
In one of those links that I posted last night (of the websites showing different pics of Lindsay and Sam at DLR from the last year), there was a picture of Lindsay and Sam before they arrived at DLR this week, but from the same day, I think. Did anyone notice that in the shot of L & S sitting in a car (before the OP saw them at DLR), Lindsay's face just looked a wreck? I don't know if she had been fighting, getting sick, crying or sleeping, or maybe she hadn't slept at all in days, but she looked a mess......like she was, at some point....maybe, possibly, perhaps....er, um.....in an altered state. And then they went to DLR after that bad picture was taken, and apparently, from what the OP said, the possible altered state continued on through Soarin' and beyond!! Wow! That's hardcore. She was (possibly, maybe) messed up beforehand and decided to just go to DLR, and then people witnessed her acting/looking messed up there too. I guess DLR must be Lindsay's happy place too, like it is for all of us!!
I find it funny and sad that Lindsay constantly reveals what she is up to in photographs - even if she doesn't know they are being taken, she is constantly being caught on film doing something that makes her look bad - but when she is caught red-handed, she denies it. She was recently shown in a London paper with a certain white, powdery substance IN HER NOSE - it was very clear in the photos - and she denied it by saying it wasn't what it looked like (it never is): "IT WAS ONLY LINT."

And now I bet Disney is probably regretting that this fine role model for kids (Lindsay) was in any of their movies and is now being photographed with "LINT" in her nose and then at
Disneyland!!!
