Very much so, RAS- I don't care were you are, if you've got subways or commuter trains, you can get the windows and/or doors open without tools. Fire safety issue.

Yes, following the two or three steps on the sign labeled "in case of fire" isn't as dashing as smashing the window open, but it's liable to either be faster than trying to smash safety glass or less likely to induce major bleeding if you do get it open.

Andy - I will have to look at my HT when I get home (I am on a business trip) to see if it has wideband receive. Do you also commute to Philly?

Art_in_FL - 90% of the time I wear cotton chinos and either a Polo shirt or button down shirt and no tie. In a crowd I look like most other men so I blend in pretty well. Good idea about the TP. Thank you.

Brangdon - My train commute is less than 10 minutes and 1/2 of that is above ground. I am confident that, assuming the train tunnel wasn't collapsed I could get out fairly quickly. That said, I am considering carrying a small water bottle. And definitly considering a headlamp or band to convert a light to headlamp. I am looking at a small pry bar that was recommended by another poster. Thank you.

Sherpadog - Oh, good point. I was focused on intake, and hadn't considered outflow

thechaplain - Good idea, and if I was commuting through areas that I didn't know I would carry one. For my commute, I think a compass will be enough.

Ironraven and RAS - I agree completely. The windows are designed to be opened without shattering; it is a safety issue. And I find myself compulsively reading the those instructing whenever I get on a new public transit vehicle.

Again, thanks everyone for the suggestions!

Now all you need is footwear (shoes/boots and socks) designed for long distance walking
