I found someone's allotment blog here a few weeks ago. Unfortunately
I have had to re-install Windows so have lost the URL. I've looked at
recent posts but just can't find it.

I can remember:

There were a number of photos of the allotment (it may have actually
been two plots together)
It was part of an allotment web-page circle.
The "owner" had just put up some very strong supports for his/her
runner beans - not just canes - looked by 1x1 timber
He/she had already transplanted some broad beans which looked really
healthy.
He/she had some photos of lettuces set out in a pattern of different
coloured leaves.
The sweet-peas looked really healthy.

I would be interested in a pointer to the web-page.
