Actually, driving through D.C. recently I saw a ton of white vans.
Got to thinking, how many of them are workers and how many of them are 'keeping an eye on things'.
Not to sound conspirational, but you'd think at least some of them might be surveillance vans.
Definitely watch too many movies.
Last night, my wife and I went out to dinner. While at a stop light, I looked one lane over and saw a white van, with a roof rack and the left tail light was out.
Lol, insert "Twilight Zone" music here. There are a zillion white vans out there!
