The most memorable series I have done is the now archived Northern Maine Woods Virtual Tour - Maine's first extensive cache series. While a few of the stops may have appeared mundane, the series as a whole took enough effort that made it memorable and the journey along the way was what this series was all about. It makes it more of an accomplishment for Lee and I since we were only two of no more than six cachers who found all 7 stages of this cache in the 5 years that the series was available. Those that passed up #6 missed out on an interesting stop.

While not by series by name, we have enjoyed the puzzle caches of Laughing Terry's that we have done. Most are distinctly memorable, which is a good feature of a series. All the puzzles are different, and the hides vary as well.

The zoo series is a nice one for kids. Especially since all the caches are in one area accessible from one parking location.

Of the series that have many caches, The Maine Rose and Rt. 2 Tour are at the top. I think the hides for those have been done less haphazardly, most likely because they were hidden by a select number of cachers. We still have some more to do on each of those. The problem I have with the larger series is that it's hard for an individual stop to be memorable. I may remember that one of the "Beers of the World" series was near a nice pond, but I won't remember it was "Beers of the World #156 - Cuvée Ermesinde", and I probably won't even remember where is was.

Personally, I would rather see the smaller series be multis than separate caches. But, I know that would cut down on the number of people who would look for it; why fnd one 10 stage multi when you can get 10 smileys?
