So, here's the dilemma: On the one hand (call it the right hand) I would like to clear up all caches within 10km of my home coordinates. On the other hand (call it my left hand) here's a whole bunch of caches that would facilitate completion of one of my more obscure daily grids. So don't read anything too sinister into me picking up your Unknown/Micros one at a time, it's just my left hand currently winning the argument.
The puzzle, after the initial confusion was sorted out, proved pretty straightforward, though I used online resources rather than a spreadsheet. A quick find at GZ with a strong hint guiding you in (though my GPS did say 12m to go).
