Can't fix stupid.
Easy making comments about a 65 year old veteran from your armchair.
There are many miners that work or explore alone. Been that way forever.
His friend said “we have an agreement when it comes to these mine shafts”. His friend apparently knew exactly where to go looking.
The ground under him likely collapsed into the shaft.
Not trying to offend with my statement. Working "alone" is fine when even the most minor safety equipment and protocol's are not called for (working in an office; selling used cars) however, checking out mine shafts in the Arizona desert by yourself, falls into the "moron" category in my never humble opinion. My armchair has a whole lot of experience in the Arizona desert. Pulled another Cholla spine out of it last week.
