One of these links caused me to read about a jostle sensitivity alarm, I actually have one, forgot all about it. Funny enough I bought it back when I used to backpack, I set it to scare of any animals wanting to get into my pack. I'll have to look for it. Couldn't hurt to add to the current system, being that I already own it.

Anybody got any non-childhood experience with one? Is it a good idea, or will it just annoy the smokers? My workplace bike rack is right next to a smoke pit, which I like for the high traffic area part, I might lose a seat to a hot ash fire though, lol. I mean I don't want people damaging my bike because its annoying. Thoughts?
