Question about LP convention

I have never been to an LP state or national convention. From those of
you that have, I'm interested in knowing which of the following you
have ever seen done there:

1. Presentation of colors, (the US flag), such as by some local ROTC
unit for example
2. Pledge of allegiance
3. Opening prayer

I was at the 2006 national convention in Portland. I got their
mid-day, so I don't know about any of this. But let me tell you that
if I heard them open with the pledge of allegiance, _especially_ if
they said "under God", or if they opened with a prayer, I would walk
out of there in a heart beat. I want sensibly practical politics -
not superstition.
