A really great idea for a challenge. This was the first of the Explorer series of challenges and I remember running the macro when it came out and finding that we still hadn't reached 100 squares. Although I live north of here in the Explorer 145 region I thought we'd be a bit closer than that given all the visits we'd made for MrCryptic and Natterjacktoad caches. However I much prefer a challenge that I'm not already qualified for (because then it isn't a challenge is it).
We've gradually been picking off squares since then. I had another check on the macro earlier this year and found that we'd reached 120 so we just needed a final push. Selborne was a big empty region for us, and so we finished up with some church micros and old caches in that area. We are now on 137 so we came to pick it up this evening.
We started looking in the wrong place (under the tree) but once we'd read the hint properly it was an easy find. Good to see an ammo can - this one was absolutely packed with goodies and it was hard to fit it all back in. We swapped a bangle for the Wildlife Top Trumps. A lovely area for a cache - some great trees, birds singing, very peaceful - so we explored a bit before we left.
