FORUM RULE: NO LOCATION SPECIFICS IN COMMENTS, ONLY BY PM.
Feel free to share specific locations (e.g. entry points, names of sensitive places) by PM, but not in posts or comments. Of course this does not apply to what's on outside links.
This rule is not out of bloody-minded elitism, but to prevent destructive hosers from finding places too easily and trashing them. Remember that reddit is indexed by search engines.
And please, please, don't steal. It's not cool and you make us look bad.
Please avoid posting "Anyone know any places to explore in ___?" You would be much better off asking your local subreddit, google or other resources like uer.ca to find them.
