Randjack, I looked through prior posts and while some of Livestrong's questions are certainly, well, somewhat atypical of this forum, I don't see anything about sex. Was there a post I didn't see?

Livestrong, there is no magical method of emergency communication. If you are concerned about the cell phone battery dying you could carry a Sidewinder Cell Phone Charger. My wife got me one and I carry it in my "urban EDC bag". I'm not sure where she got it from but it is available at http://www.aeromedix.com - the same people who sell Doug Ritter's knives & Photon Freedom Microlight.

Beyond that, unless you have a ham radio or higher end communication gear you are in a position to rely on the methods you aren't interested in hearing about. FRS and GMRS radios don't transmit very far and the frequencies don't tend to be monitored for emergencies, but I guess you could get lucky.

You're back to whistles, mirrors, fire, smoke, flares, bright flags, and other signaling techniques. In New Orleans it looked like those stuck in/on flooded houses made great use of spray paint to signal for help.
