What's the obsession with the strip club? It's irrelevant.

From the AP article:
The explosion in a downtown area of Springfield, 90 miles west of Boston, blew out all windows in a three-block radius, leaving three more buildings irreparably damaged and prompting emergency workers to evacuate a six-story apartment building that was buckling.

This could apply to any professional workplace in any downtown area.

The ladies who posted nailed down the essential problem: there is no practical way for a woman in professional garb to schlep a bunch of hardware around on her person. Probably not a substantial purse either.

But footwear is a good place to start. A laptop bag offers possibilities. So does the addition of N95 masks to the first aid kits that seem to be in many places on an office floor. More stuff at the desk and in the main purse. And as suggested previously, a complete car kit.
