Hi Merlin,
Yes you're right about him being out by approx' 2/3 years, but when you're talking of a timespan of 16.4 billion years, hey! what's a year or two. That could also be the PTB trying to paper over the cracks, but inevitably their whole scheme is and will disintegrate, which is now becoming apparent. It just put things into perspective for me personnally.
Regarding that meeting up point after everything goes pearshape. Feardia posted something a couple of weeks ago on the predictions of Colmcille, which more or less stated that the only places above water would be parts of Kerry/Cork and Donegal/parts of Antrim. The rest flooded or bog.
A bit gloomy, but sure it's anybody guess!
Seeing as how people seem reluctant to talk on here, which is disappointing after an initial good response two weeks ago, it would be a good idea to state a
couple of meeting places just in case the prime location is not accessible for some unforeseen reason.
Any & all suggestions would be helpful.., especially from the Irish
lurkers 
Tom.
