I recall, when I first heard about this series, that it sounded interesting but there was no way that I would ever complete it! However, things change and some time later, after I had the local ones under my belt, I started to think about it more seriously. First there was the holiday in Cornwall which with relatively little effort gave me four for the week (Somerset going and Devon and Dorset coming back). A few more were picked up opportunistically and then there was the time I cirmnavigated Londen (something over 250 miles) and picked up six home counties in a day. By now I was admitting to myself that I was hooked and started to give some serious thought to how to get the rest. A week's geocaching (covering over a 1000 miles) gave me the six Northernmost (and quite a few others caches as well). Another two day trip West give me numbers 45, 46 and 47 (plus "The First in Wales" and a whole bunch a Church Micros http://www.15ddv.me.uk/geo/cm/cm.html another series I am a great fan of). An exchange of emails confirms I have correctly added up the numbers and am good to go. Just one problem, the parking spot is a four hour drive away! My non-caching partner, bless her, provided the answer. After Christmas with her family we headed further North for a two day stay at the "Last Drop" hotel which made it a simple stop off to visit an area familiar to her (being originally a Manchester lass) and to attempt the cache. It has to be said, it put up a good fight but after more than 10 minutes a critical element of the hint was spotted and the cache retrieved moments later, to my great relief. This has been a fine challenge and I a very pleased to have finished in the first 20 finders. I've thought about which was my favourite but it would be invideous to single one out. Likewise I will forebear to mention those with which I was disappointed.
PS. In case anyone's wonder "What next?", I still have (too?) much in my sights. Just see my web page http://www.15ddv.me.uk/geo/chal/index.html
