Eugene:

Funny you raise the question. See the earlier thread on shirt-and-tie PSK's. A PSK, as I imagine it, would include items that would have little use or relevance in an urban setting. (Please don't slam me on this. Read the posts in that thread.) I'm not going to carry that stuff because: 1) it's not relevent; 2) I can store it close by; and 3) the vicissitudes of modern life (magnetometers, etc.) make carrying that stuff inconvenient, to say the least.

It's dependent upon the situation and location. I won't carry a gas mask in Las Vegas, but I might have one in DC, or at least have a NIOSH-approved mask. That's my opinion.

Regards,
