Ignorant hypothetical question from a non-radio person, but if I were floating down a street in the Ninth Ward of NO looking for survivors in my boat, would that be a legal use of the marine band even though I'm actually in a city? I know, a rather irrelevant technicality in such a situation, but I was just wondering about the general legality.

And if I were stuck on a flooded rooftop in NO (without a cell phone) with Coast Guard and National Guard helos flying overhead, which would they be most likely/able to hear: my FRS, GMRS, HT, or marine radio distress call? I know, I could wave my arms and such, but that's so primitive. I mean, there's no gear involved! <img src="/images/graemlins/wink.gif" alt="" />
