Colin,
Glad you got to your first show. I am really looking forward to see a couple this year. Do you have any pictures of your new Catt? Please share with the rest of us.
One explanation for what orchids you did see at the show would be what was in bloom/season. Remember that different orchids have different growing and blooming seasons.
The wrinkled leaves I believe are usually a sign of lack of water. I believe when exposed to too much sun then you will see red pigmentation in the leaves then the leaves will begin to pale due to loss of chlorophyll.
