Jetskis irk the heck out of me, but I figured it was just a matter of personal distaste. Shoulda' figured I could get all self-righteous about it.
I don't like the noise, a lot of people who use them on the lake we go to are very reckless with them, and they ride them dangerously close to beaches where people are swimming.
I so didn't realize I could get pissy about disrupted surface tension too
