Make sure that once you register your camp that you click on the green button to set borders. This is solely used to get GPS coordinates for the weather data. Once you save the border you must set up items on the map so click the green button again. This will save the map to your camp wall.
One other tip, you can store data for years past. The sighting feature will grab weather data for up to 5 years in the past. You can import pictures and BGL will automatically grab the time and date. Click next and it will store the weather as well. So start loading data into the system. The more data you store, the better you can pattern the deer.
