At one point in the past, I dried mine out and put it in an envelope in a drawer. I was able to reconstitute it from this at a later point. The starter I have came from here: http://carlsfriends.net, for anyone interested in sourcing their own.

Also really interesting. I would be curious to know whether both yeast and bacteria survived in this dried setup.

I tried it based on stories I'd heard about old timers using it as the mortar in log cabins between the logs, and later reconstituted. Don't know if anything really survives or not, but I was able to get it to rise and make bread so...
