Well, for what it's worth, I called the tower and asked about the
clearance. The tower supervisor I spoke to said they ALWAYS assign the
SID. If the clearance delivery guy didn't read me the SID, he goofed.
If he did but I just didn't hear it, I goofed. If I read it back
without the SID and he didn't correct me, he goofed. One way or
another, if I didn't have the SID written down, somebody goofed
somewhere.

I imagine we could have pulled the tapes and listend to them, but it
just didn't seem worthwhile going to that trouble.
