I'm happy to use a Doodle poll if you set one up, @johnwilliams_6. (Setting it up is beyond me!)
Meanwhile, it currently looks as if I could be at the Bap Cafe on 23rd and 30th July, and all of August without the usual time restraint. (No Pilates.) It's a special journey, so I shall look here and see if anyone else is planning to go before I make the effort. (Anyone for 23rd?)
I am otherwise occupied on Thursdays 2nd and 9th and maybe 23rd August, but might be available on 16th and 30th.
Wednesdays or Fridays (daytime) are sometimes possible, but not evenings. Tuesdays rarely.
