Oh dear...
Hesiod has a very interesting and mildly troubling post about the possibility of domestic terrorism this weekend. April 19, 2003 is the 10th anniversary of the storming of the Branch Davidian compound, and the 8th anniversary of the Oklahoma City bombing. I'll probably do what I planned on doing this weekend anyway, which is staying in and rebuilding my home PC. Stay safe, y'all.
