Yeah I found that map and downloaded it the other day. If not for that map I'd probably be lost somewhere on the east side of the map.
I'm pretty sure I've been through Clay Harbor but didn't see any clay. I'll have to wander back the coast and look around again. Knowing myself there's probably a giant neon sign saying "Free Clay" with an arrow.
As for the mines, if they aren't closed up with door, would they be considered public?
Thanks.
