Agreed. When I received my NEXUS card they explicity told me if I was traveling to a conference and was presenting that I would require additional paperwork, possibly including a letter of invitation, and/or a visa. I presume if I were presenting at an IETF WG I would check the appropriate box when registering as well and I would get the paperwork. I've also been detained upon re-entering the US for more than an hour with my entire family recently crossing the land border. This was not a fun experience. Either way, I'm waiting to hear the report from Leslie et al from people based on the survey questions asked. They seemed quite comprehensive. - Jared -- Jared Mauch | pgp key available via finger from jared@xxxxxxxxxxxxxxx clue++; | http://puck.nether.net/~jared/ My statements are only mine.
