Numerological Predictions

In the 9/11 conspiracy forum, there's a thread discussing the possibility of another 9/11 like event.

This got me thinking. If you are either (a) a terrorist or (b) an evil government or (c) miscellaneous perpetrator of such an event, what day would you pick and why?

There have been many posts on the significance of 9/11, the fact that it was an anniversary for various things, etc.. so my question is, regardless of what you may or may not believe about 9/11 or the subject of numerology, what anniversaries or 'special' dates are there that you believe conspirators would choose for another large scale attack?

Easy, if I were Subcommandante Marcos, I would seriously be considering a terrorist attack on December 21, 2012. He comes from the Mayan heartland, such an attack would have huge significance.

There are many potential dates that could be ideal for terrorists to strike. Major holidays are always potential targets...

I think christmas and the 4th of july would be major target dates.

Also you have the sketch days like 4/20 of course.

thinking as either a governmental type who wants to scare his people (worse) or as a terrorist maniac who wants to keep people living their lives in fear (both the same thing really), I'd probably pick a completely random day with no significance, so that people would always be scared ****less, regardless of whether it was a special occasion or not.
