Tonight (2/7/12) I came home from dinner around 8:45pm and there was a "salesman" waiting for me at the front door. He immediately started a show and tell about a product that would clean my dirty tires. I was suspicious, told him I wasn't interested, and he walked down the hill.
At best, he may indeed be a real salesman (with very bad judgment). At worst, he did (or would have done) something illegal. I didn't notice anything wrong with my house, so I don't know what his intentions were. Not to cry wolf, but it is a bit creepy to come home and see someone at your front door on a dark damp evening.
Just wanted to share that, so others can be alert.
