Imagine if they built a nicer-looking box around each metal box. Something with wood construction and a little roof, maybe - in any case consistent with the architecture/esthetics of the surrounding houses. It could look like a like a sort of gate-house, like the ones occasionally seen in upscale areas. This could be done for $1500 per box.
Just an idea - maybe this would satisfy complainers enough to lessen an obstacle to better, faster internet.
