I know I am a newbie to geocaching..... but is there different criteria for winter caching? I would prefer to look for cache that are in trees or some how above ground. I don't think that my gps is accurate enough for the under the snow stuff (I could be digging for days ). Living in Northern Minnesota, the snow is expected sometime this week. Let me know what you think. Thx JimJax and the 3 dogs.
