You've found some nice bits there ktmman.
My lovely daughter is satisfied picking up bits of gravel and the like as she finds it, even when they all look the same. I don't think she'll be too stressed if she doesn't find any actual crystals :lol: To be honest I'm more worried about my partner and keeping his interest up, lol.
We're thinking of heading up to mount hay too, so might do one each weekend (my father is up visiting too so will be good to take him somewhere new).
