Hold on.... Don't think that if you are a ham and want to pour coffee or whatever that you shouldn't do it because you are a ham.
If you want to pour coffee, setup cots, or whatever, DO IT. If you want to be a registered volunteer for Red Cross, ARES, CERT, SAR and the dog catcher, by all means get after it. Actually caring for displaced pets and animals is a fine thing to be doing.
What I am getting at is specifically about ARES and the number of hams that I hear complain about showing up with their radios only to be told to put them away because the communications and technology portions of the disaster are covered and their help is not required. When you get into that situation, you need to have a different path to take, other than the one back home.
So my point is that we are not doctors or nurses, except for those of us that actually ARE doctors and nurses every day. So our skill set is not as valuable as it once was. We need a new skill set to bring to the table as ARES. And it's not that putting together charging kiosks with a WiFi access point and mesh backhaul to the web is difficult. But if no one else is doing it, then we can be. AND when you present that, not only to the EMA / Red Cross folks, but to the public at large, you will gain some interest in WHAT we do as hams, and maybe a few members as well. And THAT is a positive thing.
But for all those reading this, again, if you are capable and comfortable with putting down the radio, and just doing whatever, by all means do it.
People anymore as a rule seem to want to take advantage as much as possible. And when the Red Cross asks for volunteers from the displaced, very few hands go up. So fill that void. For those that want to pound your fist against the table and publicly make yourself look silly while ranting about how no one listened to the hams during Katrina (I personally witnessed this) then you need to have something to make yourself feel needed. Or if your not that die hard, but still want to do something of a technical nature, then this sort of stuff fills that void.
