If you're into using Google Earth you can do a copy/paste with these coordinates (25 40.648s, 48 34.920w) into (I think the field is called) "Fly to ..." and press Enter. You shouldn't have to change anything as far as the coordinates are concerned, just simply copy and paste. You'll end up looking down on Chris and Karen's 'Farm'. The image is blurry but you can get an idea of the relationship to other parts of Brazil as well as the world in general. It's about 15 kms. west of where we're staying on the coast in Matinhos.
If you haven't started using Google Earth, get with it. It's a fantastic way to spend your idle hours; looking at places you've been to and checking out places you want to go (as well as finding places you don't want to go!).
You can download it for free from Google Earth.
