Mike, perhaps you missed my point.
Basically, they are not too hard to keep alive for a day, as Derrick is planning.
If held accountable for specifics, the only thing I would change in re-reading my note is the water amount. I was thinking less than an inch of water with the seaweed to keep them wet, but typed "a few". Oops. I wasn't thinking specifically enough in my reply.
I'm actually surprised at the response this simple request received. Us "diehards" will debate anything, huh!?
