This is slightly off-topic, but have you heard of geocaching? It's a high-tech hide-and-seek game where you use your GPS to find a treasure box or "cache", then claim the "find" and exchange trinkets? It might be a fun use for that fancy hand-held GPS unit you just bought. And you could also hide a "geocache" treasure on or near your maple operation to lure potential customers. While they are not allowed to be explicitly commercial they can let people know about your retail location (if you have one). Our family has been doing it for a year now and we love it. It brings us to cool interesting sites that we would have never have gone to otherwise. The website where you can look up geocaches near you is http://www.geocaching.com (I'm MapleDave on there).
