I have been a avid reader of this forum for awhile, I produce a web site http://www.campsandvans.com
where I produce POI (waypoints) for many GPS systems & PC programs such as Map Source, Base Camp, Ozi Explorer & Memory Map etc.
I am offering members of this forum a discount of $5 on the normal membership fee.
If you have a good look at my web site you will see that it is very comprehensive and lists Caravan Parks, Camps & Dump sites.
If you would like to contact me to discuss, please do.
