Geocaching is our main hobby. Like all hobbies, there is cost involved. Take an avid fisherman. He'll spend $50,000 on a bass boat and won't think twice about it. If your a geocacher with a lot of money, you can travel the world and geocache. If you're a starving mapper like myself, you can see a few states. Regardless of how much you spend, it's about having fun and making new friends!
