Actually a military base would be more fun to observe than my house. Thats probably why I havent seen any around here....
On the other hand, I have new neighbors behind me and the husband is really weird. Every morning for some reason he leaves the house at about 5:30 a.m. and doesnt return till about 3:30 in the afternoon. Very Strange!!!
Keep a close eye on him. He might be an alien living among us!
