Alas and alack, can't do the 11th June either. I hope it goes well though and everyone has a lovely time.
Perhaps if enough folk are willing and able there will be more of these Vernon Do's around the country.
Maybe other university towns/cities, Leeds, London. Edinburgh. Manchester. Coventry. Nottingham. Glasgow. Birmingham. Oxford, Newcastle, Canterbury. Not all in one year obviously.
I'd be up for facilitating one in Oxford, lots of nice parks and picnic places, and the Thames, there's a nice Pieminister in the Covered Market too.
