You actually don't have to spend anywhere near the money that this gadget probably costs. All you need is a good stereo system, and tune it to classical music. Keeps the damn buggers away as well.
I used to drive a bus for a summer camp. The year in question they had a mini bus along with the bigger ones. I had a small group in for a tour of the local newspaper in concord, nh. I finished early, and went back and sat in the bus waiting for the group to come out. It had a radio and I had it tuned to the local pbs station and classical music. One of the kids came out, without the others, and got on. He listened for a few seconds, and then without a by-your-leave, switched it to some rock and roll garbage. (sorry to you rock and roll fans out there.) I immediately switched it back to my station. He actually had the audacity to say 'Hey, I am listening to that,"; whereupon he got read the riot act. It's my bus, he can listen to whatever he wants when he gets home, but for the time being, it's my bus and I'm listening to it. Other times I have to tune his type of crap out but for the moment: Beethoven rules!
cheeky little bugger..
to top it off, one of them stole two box cutters. I found one on the bus and later returned it, but they never did find the second one.
The parunts can't stand them all school year so they dump them at summer camp. Of course they do it 'for the children'.
HA
like some classical
