sorry for not replying earlier.....been lying on the beach in Mexico drinking beer!
If it helps and isn't too late......
I went to the local cop station and they told me the same thing.
I then went to the records department at the court house. I found out who opened the mail and spoke very nicely to her and explained the situation. She said she would keep an eye out for the letter, and then I got the airline to post the forms to her.
I phoned her about 3 days after the airline said they'd mailed the stuff off, and she said it had arrived. Went in, got fingerprinted, and they put the return envelope (already stamped) in their out box. Couldn't have been simpler.
Good luck at chatauqua.....I start with ASA on 6th December.
