Hi Guys,
I think it would be fair to say that this discussion has left me totally
confused ... I think I got lost with the subject line :)
Please would somebody care to explain exactly what is being talked about
here - for example, is this simply a discussion about Foxton or does it
concern *all* locks with a side pound?
I thought I'd got locks sorted out but I'm obviously missing something
here (I've been assuming that the 'reds' and the 'whites' are different
coloured paddles, each taking water from different sources) ... remember
- words of one syllable will help enormously :)
Cheers,
Trevor
