Warlock,
I must admit it's nice to see sites in a manicured condition, but failing that, it's not too good to see them overgrown.
The site (any site) in its original condition, and when in use, obviously wouldn't be overgrown to the extent where the stones were becoming obscured. Originally I'd assume the site was pristeen, but after a few years of use, I'd think some growth would be left, unless gardeners were put to use.
Do you or any other TMA-ers have any thoughts as to how well gardened a site was kept when in use in the past, or was it kept clear simply by people walking over it?
Cheers,
TE.
