Could it Be WiFi / Gremlins in the Air?
Just throwing this thought out there , don't know if it's even possible... There's been a lot of flack over the Rail Crossing in South Ottawa... The Flashing Light / WigWag and Barrier have continuously Malfunctioned... Unfortunately it took the Death of 6 people in a Bus colliding with a Via Train to make this Front Page News..
With WiFi, Radio Waves and all.. Could it be Possible when the Signal is tripped somehow , if you get where I'm going with this.. In the back of my mind I think of Garage Doors in the neighborhood opening on their own when someone else next door has Nuc'd something in their Microwave... Just Curious... Cheers
