Geocaching

So a while ago I got into geocaching, without a GPS receiver device.
As a result, I haven't really been geocaching much in the last few months. It takes a lot of work to look up the location of each cache, plot them into google maps, and then pre-load the map images. I can't just randomly decide that I'm bored, whip out a GPSr, and just go geocaching wherever I am.

Which is a pity.

Perhaps I should just go buy a GPSr. I mean, it's going to be difficult getting coordinates for when I end up finally placing that cache otherwise.
