Megadread (and other relatively new contributors),
You may not be aware but there is a Facilities section to TMA. Rather than adding your campsite here,
http://www.themodernantiquarian.com/post/69388/links/rudston_monolith.html
just choose 'add facility' from the Add menu on the Rudston page, and add the details in the boxes.
You will also see on each site page (where a facility has been added within 20 miles) there is a 'nearby facilities' drop down menu in the centre of the page from which you can view nearby campsites, museums, cafes etc. .
I'll let you move the details across so that they stay under your name.
Thanks,
TMA Ed.
