Over the past three years I have spent much time deep in the greenbelt of west Austin and I have come to learn of a great number of creatures that live there.
I recently came across a flash drive with some jumbled GPS data wrapped in a letter requesting urgent assistance. With a little help I managed to decipher a few coordinates and fashion a Wherigo Cartridge to direct you to a starting local, but I alas have been called away on a business matter and cannot myself respond.
The friendship I have forged with the inhabitants of the western hills has been hard fought, and should you choose to come to their aid, you should expect a long and arduous struggle. Many days and difficulties await you, and those not willing a great deal of physical and mental exertion should just pass by.
Good Luck.
Note: This is a long and difficult cache series. Take all the gear you'll need for a full day of hiking around a greenbelt. You may never find the final cache, and one day may not be enough. Despite the ironic name, small children are not advised. Happy Caching, John.
