What a great challenge. I noticed it soon after it was published (I started on 15/10/11) and by Halloween I'd done a couple of logs showing I'd almost had a line (E2-D2-D1-C1-B1). Over Easter we did a series by bike (A1) near Bracknell and so had completed a line across.
Of course I had a few other squares done too by that time, but none were connecting. Then I went to the Geolympix in July (meeting RubyShoos herself at most of the caches I did). That gave me a few more squares and I now see that I've now done 17 of the 25, with all but one of them connecting.
See my webpage for the qualifying caches for each of the sub-challenges.
Bobcat and I decided to pick this cache up today (and at the same time try for some other RubyShoos challenges that we'd qualified for). But how could I sell it to my (non-caching) wife? An afternoon at Bluewater!! (I hope it doesn't end up too costly).
The cache was a nice easy find. We needed to be careful to be unnoticed as there were two girls sunbathing/picnicking on the grass next to the roundabout (of all the places to choose).
