Hi Petra! Glad you enjoyed and picked up something, just had to question the startement that are more persons working on earthquake prediction than at mcDonald's. I wish it was true but can't see that. I do see a wage parallel, however. There is no minimum wage for earthquake forecasting at present! Take care, and when you want to change the stored water supply from time to time, you could offer the water to friends with aquariums, as it is probably naturally de-chlorinated from sitting a while. Be great for changing the fish water, also probably already room temp >='/=> ...mb.
