the streets of NY

When you are out in NY going far and wide on all streets and avenues you soon get very aware of the poor shape of the tarmac and asphalt of the streets. At times you long for Sörmlandish wood roads which in comparison seem flat and even although they still have more patches. I think it is the heavy vehicles that make the wave like ridges, the potholes on the other hand probably has something to do with the heavy rains that drench the city from time to time. But it is the practise to use blocks of concrete and sharp edged metal well lids and such that hurts me and my bike the worst. Right now Madison Avenue has new and very nice asphalt, how ling will it last?
