Then do it the old-fashioned way! Grab some friends and make it a group adventure! Ideal for urban caches, but be careful of going into unknown areas without at least a cellphone or telling someone before hand.
Step 1: Geocache Prep
Then go [www.geocaching.com here] and input your area code. Browse the options available and choose a couplka difficulty level
Now, it is best to write down the title given to the particular cache because without coordinates, there aren't many resources available and the title can be a HUGE clue. Some will even have additional clues that you will also write down and bless for making the adventure a little less frustrating.
Peruse the accompanying map to the closest zoom level so you have a good idea of the area. Try to find any landmarks in the area for extra guidance.
Again, make sure to write it all down!
