My CERT had a drill with the city fire department a month or two ago where we pretended to hand out Cipro - we left door knob hangers of information on CERT - in a selected area of town. It was fairly realistic as such things go. The goal was to see how many doors we could hang hangers on in what amount of time. Not realistic if we were handing out Cipro, but still a way to judge coverage by volunteers.

Great fun and good training. We used ham radios to let net control and the fire guys know what all was going on. The FDA has a press release at
http:/www.fda.gov/bbs/topics/NEWS/2009/NEW02002.html
where it spells out how it will allow volunteers to distribute prescription medicine and allow off-label uses in certain circumstances; this press release is specific to Relenza and Tamiflu, by the way, but our training presumed an anthrax attack, and I presume the same procedures would apply.

Nobody in my area (San Francisco Bay) panicked; people complained about school closures; school closures stopped; life went on.
