Black Triangle Sighting in Valleyview, Alberta on April 5th 2014 – huge triangle with pulsating red-orange light

I was traveling from Grande Prairie AB to Edmonton AB @ approx 12:30am - 1:30 am. I had passed Valley View AB traveling southbound on Hwy 43. I noticed on the east side of the Hwy a light in the distance.. as I continued down the Hwy the object got bigger. My first though it was ace phone tower. but as i got closer to it and was beside it i coould see the actual size of it was HUGE! it was a huge slow spinning triangle probably 2 storys tall and the lights were coming off of the corner columns that were twice as tall as the actual craft. In other words the corners were the tallest part at roughly 4 storys. At first i was still trying to comprehend what i was looking at then the lights started to pulse as it spun and the light then started (my best description) to drip off of the corners and change colors. the dripping colors then faded before the hit the ground. when i saw that and clued in to the fact that this was not from our world i got very scared. I was on a Hwy very late at night and only a couple people had passed by. no one slowed down like i did tho... i was the only one that had stopped to get a better look at this thing. I then stepped on the gas and got out of there quickly... it didn't pursue me and the last time i saw it was as I sped away...
