Glad to hear you're alright.
If it makes you feel any better, I was going down a very steep hill the other day at night, some snow had melted during the day but had frozen over the road at night... anyways going down the hill, hit the bottom... complete black ice... I was only going like 40km (steep hill, was 1/2 expecting ice), car kept going forward, there was a 90 degree turn at the bottom of the hill.... car started to turn, but my right tire went over the curb, got traction and then corrected myself... came back down off the curb and out of the ice.
Luckily no damage, didn't hit the curb too hard, and it was a low curb. Just glad I missed the trees and the drop on the other side of the curb... lets just say I wouldn't have been able to put 2 tires over the curb.
Sometimes it'* close calls like that, that make us wake up and realize what could have happened.
