Sorry Kieth, but if you haven't got transport, getting high is quite a fair distance away from Calis and so one would need quite a bit of warning. One interesting fact to note with the devastation in Japan is, most of the buildings there are almost wholly constructed from wood and so getting upstairs, in Calis, might , should the need ever arise, be a very good idea. Anyway, it doesn't bear thinking about and it won't be high on my list of worries when I next visit.
