Shame,
The first 'Third Monday' clashed with the World Sci-Fi con in London.
Might be able to pick up future events though.

Interesting choice of dates, as there will be occasions (roughly one month in 7) when the fourth Tuesday will be the night after the third Monday. Is this two-nights-in-a-row planned for?

Both pubs are highly recommended!

Cheers
Nigel
