Well. at least someone is reading this...

I have had the same experience with Amazon, actually. A few years ago, when my apple crop at the farm was particularly prodigious, I went searching for books on long-term storage of fruits and vegetables(root cellar sort of stuff). Now whenever I go to Amazon they confidently offer me treatises and tracts on subjects ranging from survivalsim, to how to build your own nuclear bunker, to the by-laws of the Posse Comitatus. Makes you wonder who is out there, doesn't it?
Anyway, take a look at the google ad box at the top of the page. Ever since I wrote the piece on my trip to D.C. they have been sending ads for online "Intelligence Degrees," whatever that is, and, now, ads for bomb-detecting chemicals!!
If Amazon and Google ever get together and send their dossiers on me to the big guys, I am going to be in a world of hurt.
