I haven't had that many big caching days - at least not compared to some people. However I have managed 40 puzzles for the Forty Sortie (on 1-Aug-2012). Then a couple of weeks ago (on 20-Apr-2015) I increased this up to 50. My statistics are viewable so that this can be checked, but I'll also attach a screenshot.
I met up with another cacher - Boomshanka - at the previous cache and we decided to do the next few caches together. He was doing the circuit and I was doing the first three on the way to the Wherigo. We chatted a bit trying to figure out whether we had done any of each others caches. I thought I'd do a check. It seems I've done one his (All aboard the Gravity Express!), I can't see any he's done of mine, but he has recently done the Forty Sortie (mentioned above) which is owned by a mate of mine (who has a similar caching name) so maybe he was thinking of that.
Anyway we were still chatting when we arrived at this one. An easy find as I'd found a cache in the same place last year.
