The Challenge: You must find a cache beginning with each letter of the alphabet, for a total of 26 caches. Each cache must be hidden in Seminole County. Now, before you balk at this challenge, I've already confirmed that caches for all the letters are currently available. So, if you're having difficulty locating a particular letter, just send me a message and I'll offer some suggestions.
After finding those 26 caches, create a public bookmark list (select the Public and Shared options so everyone can see it) and include the link to that list with your Found It log, or use the challenge checker below:
Here's my Geocaching from A-Z in Seminole bookmark list as an example.
All previous finds and all cache types will count toward meeting the requirements for the challenge. If you found all 26 letters of the alphabet in Seminole County, whether it was last week or 5 years ago, then you meet the qualifications to find and log the final (just don't forget about the bookmark requirement).
All caches on your bookmark list must be located in Seminole County. Watch out for caches along county lines!
If the cache name begins with "A" it counts as your "A" cache, if it begins with "The" it counts as your "T" cache, you get the idea how this works, right? 
This challenge is open to everyone, regardless of your home state.
Caches hidden by you will not count.
You cannot us this cache for your "G" cache. No worries...there are plenty of other "G" caches to be found.
The officially recognized FTF of this challenge cache is the cacher who completes the challenge, has their bookmark list published, finds this cache and signs the log first.
Although you may sign the log at any time, you may not post a "Found it" log until you have met all of the requirements for the challenge. Until then, feel free to visit the cache, pick up or drop off trackables, and post a note for your visit.
Most importantly, HAVE FUN! Isn't that what this is supposed to be all about?? Enjoy your stroll down memory lane while building that bookmark list! 
The Cache: You are looking for a regular-sized container hidden in a wooded area off the trail. The coords may be off a bit due to the nearby power lines. Better coords are always welcome. Please remember to bring your own pen and to hide the cache as well or better than you found it. The prize for FTF is your choice of swag.
Good luck and happy caching!
