I've had 3 secondaries in my last 8 returns to the US over the last 11 months. In the previous 200+ over a 15-year period, I had 2 agricultural quick-check secondaries and 1 regular secondary, which was a retaliatory one in MIA where I was talking on my cell.

So yeah, in my experience over the last year or two, it's getting progressively worse. Lots more questioning, lots more secondaries, just a general pain in the butt.
