Thanks very much Monganaut! That actually looks really impressive on aerial views, and a pretty cool design. Sounds like it will be even better when it's ecologically 'mature' as well....
Yeah, it's a pity it isn't better known. Always fancied a visit, but it's a ways a way from where I live. I did read some time back that the designer was planning a second landscape park somewhere else (forget where) but I guess recent(ish) UK events may have got in the way.
