This cache is a replacement for sub32's Geoville Water Treatment Plant cache which has repeatedly gone missing. Hopefully this location will be better. There will usually be far fewer muggles at least.
The clues in this cache are the same as those that were in Geoville Water Treatment Plant, so if you've already found that one you will not need to find this one in order to get the coordinates for the next level of caches.
The GPSr was REALLY inconsistent the day this was hidden (jumping 50' or more in just a few seconds). The coordinates are an average over several minutes but I have less confidence in them than I do for most caches I hide so the additional hint will help you locate the correct search area in case your GPSr doesn't.
The original description for caches in this series as written by sub32 back in 2007 follows. It's all still accurate, except that there are now more than 1350 caches within 10 miles of the Capitol - slightly more than double the amount back in 2007.
Wake County is one of the nation's fastest growing counties, and in turn, is one of the most rapidly developing caching areas in the nation. With over 650 caches within 10 miles of the Capitol Building, I sometimes wonder if the city should be renamed Geoville. Well, here's my contribution to that idea. Here is a series of 21 geocaches in and around Raleigh that represent everything a growing city needs. The series works like this. There are 16 micro caches for which the coordinates are given to you. In each of those caches will be either 1 or 2 letter/number combinations. Make sure you write them down because they hold the coordinates for the next 4 caches. These 4 are regulars and should be quick and easy finds. In each of those 4 caches is a bit of the coords for the final, Geoville City Hall. The last 5 are all in the same general area, so plan on doing the final on the same trip you do the previous 4. All containers and/or locations are meant to match the name of the cache and should be pretty easy to find. Good luck!
