Tempus Fugit - Another Time Lapse

I'll be the first to say that I'm certainly as amateur as one can be when it comes to time-lapse photography, but there's something I find fascinating about this technique and I'm still having a blast with it. The following is a time lapse sequence I shot over almost 6 hours Saturday night which I've entitled, Tempus Fugit ("Time Flies"). My apologies for the tripod drift... I thought I had it cranked down nice and tight. :-)
