GTD and Event Preparation

[black.rhino]

Hello,
I have a few major conferences I am attending (not planning), and I can't quite figure out what list to put them on. Obviously they are on my calendar, but I also have some to-do items relevant to that day, as well as reference material.

Would these events be on a project list, or do people maintain separate event lists? I seem to be hitting a wall with these lately.

I call them projects with titles like "Attend Woolgrowers Conference in July" and all the actions I need to take before I go are in there.

Conferences are projects, especially because I always have to travel.
Follow-up is a project too.
