I found this picture whilst looking through for something else; taken during craning out for the survey. Tortoise looks tiny, up there.

I'll be out for a trip with an old friend the last weekend of July, but have a few days off after that, so anyone want to continue the journey with me, Sunday 30th-Wed 2nd? Will probably be working our way up the Grand Union, I.'m guessing from the Leighton Buzzard & Milton Keynes area, all easily accessible by train.

I know most of you will need to take time off work to do this, but if that's a possibility, say anyway and I'll try to let you know asap. Won't necessarily choose the first or most obvious people, but will go on flexibility and other factors too...
