Bud the Teacher

    For Christmas, my wife, who believes I already have too many gadgets (and she might be right), took one for the team and generously got me a handheld GPS receiver.  That means that I can now go geocaching.  I know, it makes me a geek that I want to do something like that, but we all know it’s true:
    I’m a geek.  One who likes being outside.  Geocaching seems like a neat twist on hiking. 
    I’ve already programmed a bunch of area caches into my receiver.  I’m planning to go out as soon as the snow melts a bit more.  Those of you that already geocache: what do I need to know or watch out for?  What’s the one thing you wish you knew before you started?
    I feel like Ralphie Parker with my BB rifle.  Let’s hope I don’t shoot my eye out.
