thanx for all the info, dave.
noumena9 posed a good question: why was this acceptable only for the bike and ped lanes? what do they use in the car lanes?
i've often thought that for such a wonderful city to bike in, NYC sure treats bikers like dirt. that's why TA is so amazing (though i have a few issues with them) by actually getting results.
on another note, the manhattan bridge rules! the bridge workers have done a wonderful job of keeping the path clear of snow and debris. and everyone on it is so friendly (maybe because they aren't getting their saddles jammed up their butts by bumps). our bridge is better than your bridge [in child's singsong voice].
