On a hot, summer day you put both of your hands on a 420-Kg yellow fire hydrant. This is attached properly to?
I have no idea how deeply you want to get into this, but there are a few types. 1. Radar motion detector 2. Glass breakage sonic detector 3. Magnetic seal break detector 4. Photocell break detector 5. Infrared heat detector I personally have a 20mm MK 15 Phalanx radar targeted close in weapon system in my living room. Manthat poor cat. I miss Boots. Oh well, mess with the bull, you get the horns. I guess that Boots didn't get the memo.
I've been wondering the same thing myself. I have always used the all weather tires and never had an issue. Last winter, however, I found that I skidded a lot more than usual, and it's been reported that this year there is a shortage of salt to treat the roads, so that is another reason it may be a good idea to look into them. I would say if you can afford them, then get them especially since you live in Vermont.
