This was about 3 days ago. As I was on my laptop websurfing and also playing some "Kool and the Gang" compilation CD, I heard an unexpected knock on my door at 7PM. So, I turned off my music, grabbed my H&K USP .40, got into a kneeling low ready stance using concealment and bellowed, "Who is there!!!". He replied, "Community Relations." I replied back, "No thanks!!!" After 5 min. of observation, I went this time to my safe room the rest of the evening in case the knock happens again. And glad it didn't.
The area I live in is pretty safe. But for some unexpected knock to happen at 7PM is strange and can happen even in upscale areas. I am going to let the landlord know about this and also buy and place a "No Soliciting Sign" on my front door.
