Thats the major problem bjm. Finding new areas that people can find even small pieces & the occasional cutter. Most people do the right thing but you do get the odd one or 2 that go back after the field trips & ruin it for the rest of us even tho it is always stated that these sites are only accessed thru hard work & negotiations & NOT open to the public after Minerama. (Pay sites being the exception.)
There are a lot of old sites that havent been visited for years & maybe the committee can look at these & negotiate access. If they need someone to visit them & test the viability I'm willing to do so. Nothing worse than going to a new site & not finding anything after travelling so far, apart from the costs involved.
