Dave, the only Greek place I've ever been to is Kefalonia. Whilst I know about the catastrophic Minoan eruption, I must confess I didn't know about Nisyros (but I do now!). I fear that Mrs Steve has got volcano fatigue, brought on by my over-enthusiastic advocacy of visiting these elemental forces of nature, but, once this horrid lockdown finally melts away we'll be off on our travels again. I'll tell her what a beautiful island it truly is but I won't mention the volcano just yet...
