A hopefully fun mystery. The cache is not at the listed coordinates. But the Flintstones used to live there.
I like to look at maps and especially at satellite maps. I use them a lot, before any hike or walk (to see about an approach or parking) or when considering a hotel, holiday house or a place to live (we organized our place form the other side of the world that way). And I have spend many many hours searching for the location of a house when you only know the suburb and have some photos of the house (in Germany they don't give you the address of the offered properties, as the buyer/renter pays the agent - you have to contact the agent to get the address). Now I hope you like looking at satellite maps too, because your job is to do something very similar. (Idea is from a Hamburg Cache)
Visit the following links and spot the places. Lets see how well you know this town. All places are in the ACT.
Place A 
Place B 
Place C 
Place D 
Place E 
Place F 
Place G 
Place H 
The cache can now be found at S 35° 1A.BCD' E 149° E.FGH'.
BTW I was going to publish this cache way back, before we left town or shortly after, in June 2012 when I put it out. But I left it too long such that I was worried it would be gone in the meantime, each year visiting I checked on it but then left to too long to publish again. But the cache was there, every time I checked and still is, untouched for 6.5 years now! This must be the longest field tested cache hide ever done. :) So here we go: I present to you the 7th and last, long forgotten cache of my Yarralumla cache series!
