I was out front, having a smoke just now, when I noticed a black, 2 door sedan parking across the street. There is no reason to park there outside the elementary school on a Sunday.
However, if you wanted to, oh, I dunno, STAKE OUT MY HOUSE, that is the only place you can see anything, as the property's surrounded by brick walls, ivy, and other view-blocking vegetation.
Curious, sez I to myself. Binoculars are for more than birdwatching, and mine were handy.
I saw two men, probably in their 20s. Both neatly groomed, the driver wearing a dress shirt and skinny tie. Did they seem to be focused on my driveway? Hard to tell. Driver's hand was out of the window. He had something in his hand, couldn't tell what it was. They sat in the car doing nothing, until they seemed to spot me w/ binocs. A van crossed between us, I took the opportunity to duck back out of sight.
As soon as the van passed, they did a U-turn and took off to the east. Just another one of those things that make you go "hmmmm."
