When I geocache, all I have is my super simple GPS. Sometimes I like to do more than one and it involves driving and a lot of remembering... but Google is there to save the day! I simply plug in the coordinates and put the GC#, size and any other hints in (parentheses ?) and head out! It is helpful for me to have those bits of information and a road map in hand.
I can input information into my GPS but with the actual unit it is a lengthy process. I can also hook the GPS to the computer and enter the info there... but I am running a Mac. There is some geocaching software out there for Macs - but I'm not going to pretend I understand them.
So Google it is!
Here is a little example I made for my sister in Florida. She is new to geocaching. You can click on the map and have a look around!
The bonus to google is Terrain view, Satellite view.... and STREETVIEW! While it might not be up-to-date... you can look around if the cache is close to the street and guess where it might be ;-) you can also select non-toll roads as well as walking directions!
PS. That is not where my sister lives ;-)
