I remember coming around a corner very quickly and I had caught this area of the curb where the asphalt and conrete had separated - trouble came quickly and then my front tire jammed in the 'slot'. The next thing I remember was being on my back in the street and watching the bike flipping end over end above me.
It certainly must have been a spectacle. This intersection was at a MARTA station (public transit) and was a pretty busy scene with people on the corner. Strange. Nobody helped or even asked if I was OK.
All my stuff went bursting into the street. I destroyed my computer & rear light and who knows what else. Miraculously, I all I suffered was a skinned knee!
