The lady I spoke with on the phone said that there was a warning at the top of the lottery webpage to only submit one application per group/trip. It may have been there, but I certainly did not see it.
On the application that won, I was listed as the first alternate and all of the dates were for June 3 or 4 (week days). I got 3 permits.
On the application that was revoked, all of the dates were for weekends in June, July, August and the first week of September, with a minimum of 5 people.
I asked her how they decided which application would be revoked. She said, we give you the most desirable dates and cancel the other app(s).
... REALLY?!?... If I meet the person that decided, I'm going to see if I can trade the them two shiny pennies for old, ratty $100 bill.
