Going to calgary to drop off my momz to the airport and saw lots of flashing lights, so I pull out my digi cam and took some pics. I'm on the highway so can't post untill I get home but all I can say is they where huge tires!! For big rigs and they where all over the place some even standing up. I don't know how the driver is doing but saw the ambulance drive away slowly, so probaly nothing critical I think its going to take awhile to clean up this mess truck on its side all mangeled up and freaking tires everywhere. Yikes. Best wishes for the driving I hope he was not drinking.
