Woof! Sense from a magistrate.
NT realy cheese me off, they play lip service to people erosion, using it as an excuse to herd them into tight concentrations that focus particularly on the sites being eroded. The yellow line business is yet another example of this crap.
Try visiting Hadrians wall (spit if you want) miles and miles of monument with a management programme deliberately designed to squeeze tourists into pay parking zones focussed on the major sites.
It is a totally stupid mentality bourne of a total lack of understandiong of both the needs of the site and the needs of the tourists. It also betrays a total lack of understanding of the economics of tourism.
