Funny how Astro isn't in this thread calling everybody rude names and inflating his own ego. Either he is formulating a theory to debunk this danger, or he's busy shilling another thread. Rest assured he will in out of his way to shill you guys. Stay strong and always question his bs. Oh and dont call him a shill because he will report you for life threatening. I have a feeling the ground around the sink hole is something to watch out for eqwise.
