Ok
You sent us many many e-mails and ICQ to verify what you need to cross here next week, either if you are driving or you are flying...
I just contacted the customs office and here is what you NEED :
2 ID Cards with photo
PLUS
Your Birth certificate
If you have this you will cross the border without any problems..
If you have a PASSPORT it is even better and faster, but the Passport IS NOT mandatory here yet for Americans...
Looking forward to meeting next week in the beautiful Quebec city for
QWEBEC Expo
