i loved listening to this piece, but i wanted more information. first, the sound was great: the interviewee's speaking style was very easy and colloquial, engaging to listen to, and the music chosen at the end complemented his voice and accent well; and there was all kinds of other nice ambient noise like shouting and hammering. the interview was also well mixed with the ambient noise. second, i thought the subject was excellent because it informed me about basic but hidden parts of daily urban life, rooftops and water. i always find it fascinating to find out how cities work. i liked how the piece focused on the workmen and how they build and maintain the tanks, however, i wish the piece would have answered more questions about the mechanics of water provision. for example, why doesn't the water or the water pipes freeze in the winter? why are the tanks made of wood and not plastic? how is it done in other cities? is this system unique to new york? is seems unusual for a water system to be so locally developed. for example, i've seen plastic water tanks used in some places. also, how come water tanks were never replaced by a higher technology system, like more powerful water pumps, rather than a labor intensive system like these water tanks? overall, it was a tight, informative, and engaging piece. thanks!
