Sorry to hear that Flip. Hope you're feeling better today
What happened to you doesn't surprise me in the least. I used to live in the Fish Creek area. Far too many teens and young adults roaming the streets late at night causing problems and property damage. And it's one reason why I moved to a small town. Unfortunately this town is growing by leaps and bounds and with it has come the same crap I left Calgary for.
Hope you find the guys and have them arrested.
