Re: Friday's night out - are we meeting for a pub meal before, or planning on cooking dinner by moonlight on the coast? We went to 'Ruby's' at Tolly D'Arcy on the autumn trip, I recall.
Btw, the tide tables say 7th Aug is just after the spring tide peak, (full-moon on 3rd) if I'm reading them correctly, but there'll still be a lot of water about, enough maybe to inundate marsh and beach beyond the sea wall, especially if the wind is onshore. And at just before 4 in the morning ... just saying!
