I knew what you meantTsyroc wrote: What I meant was that a human ship (the Enterprise) had contact with the Romulans before the Vulcans had any real contact with the Romulans.
I don't know where you were going with the Carbon Creek thing since wether it was 1957 or FC time frame humans were in contact with Vulcans long before Enterprise takes place.
I hate to be the Trek Trivia guy here, but Vulcans and Romulans
had a good bit of contact prior to "Minefield." Sometime during
the first "Q episode" of VGR, Q remarks that "Quinn" was somehow
responsible for a 100 year-long war between the Vulcans and
Romulans. Since Quinn was banished inside a comet in 2072, that'd
predate ENT by a fair margin.
Bugger it all, I can't remember that episode's name...it was actually
quite good by any standard. Janewad chewed the scenery pretty badly,
but it was an interesting concept.
