LJ, I can't answer your question, but I have to thank you for teaching me the correct spelling/pronunciation of "rollaboard." Believe it or not, all these years I thought it was "roller-board" (which didn't make much sense to me) but it must have just been the accents around me saying it that way.
You're not only a brilliant camera flyer but also useful in other ways! Haha, imagine my surprise when I saw your post show up on trending topics on flyertalk! You've been here since 2003?! That's very impressive. xo
