1786 map of area by John Cary

I've really enjoyed looking at this 1786 map of the area by John Cary, trying to decipher the roads and work out which are still here and which are now just footpaths and which have disappeared altogether. You may get a better look at the map if you click this link and then click 'larger map' at the top of the page.
(If the link goes down the info was found at www.motco.com) I believe this was part of John Cary's 15 miles around London series of maps.
