Hi Richard,
Adding to Lola's thoughts on security you might want to consider some trail cams spread around your property. You can get them fairly inexpensive online or at WalMart (apx. $50-$100 per cam). Buying 10 or so might be a good addition to your game plans. The images are quite good and stored on internal SD cards and powered by 6 or 8 AA batteries. As they say a picture is worth a thousand words!! Gives you a chance to see what's going on while you aren't there.
