on the beaches you can find a lot, also on the banks of rivers...... i do not know where you live so for that matter i cannot tell you where to look....
i think resteeming posts from other rockhounds on @rockhounds is what i would do, if i were you...
I was thinking of doing just that as I wrote my response to you! Thanks for reminding me -- I got called away from my computer and spaced it. I've resteemed your post to my blog as well!
There are a lot of places that me and my friends go, railroad tracks and trails too. I'm in Superior, WI and I live just 20 minutes away from my favorite spot on the shores of lake superior.
