With all due respect, It doesn't have a d*** thing to do with Critical Mass. It's the ******g roads here. The horrendous paving offsets are caused by the shifting black clay subgrade in the Gulf Coast area and it's called gumbo. The drought is causing it to shift and hidden paving joint gaps in the roads are the primary result, which can't be seen very well at night, btw. It's why I ride a mountain bike half the time.
Very sorry for your injuries. Get well soon.
