To get the final coordinates you'll need to take one of the CD's home and look at each jpeg picture. Each picture contains a clue.

If you need any help, or a CD, e-mail me and I'll make sure you get one! The CD also contains a spoiler pic, so you won't need much of a hint. There is alot of tree cover, but it shouldn't hurt sat reception.
