I'm up for it! Possible dates for me are:-

5/6 July
16/17 August (middle of summer hols - may not get permission!

)
6/7 September (TA commitments may scupper this one

)
27/28 September
18/19 October
8/9 November

Those are my weekends off with nothing yet booked, but I could do most Sundays if it can be done in 1 day. I'm based in Grantham, Lincolnshire and work in Nottingham so being central can get most places easily
