I just looked at the webcam pics on
http://www.rememberthespectrum.com/. This complex isn't worth the I-beams holding it up. It's always the hope that what we build thoughtfully improves upon what was there before, but this? What a big step backwards. While I don't believe that the Spectrum was great architecture, it had its place and had earned respectability though years of use.
Tearing down that arena was the least creative thing that could have been done. Was there ever any thought to turn the arena over to public use? I just spent about 15 minutes looking at old Spectrum photos and have come up with a handful of interesting ways to reuse this structure. Imagine bringing your kid to skate in at the Spectrum before going to see a Fliers game. Pick-up basketball games at the Spectrum anyone? Ring the complex with some retail and integrate it into a larger development. Such a shame.
Some might say that these ideas would have been cost prohibitive for a profit-driven developer. Well, if ever there was a good time for the government to come in and work with a developer to find a good use for the facility, then this was it. The "market" was left to its own devices and now we have to live with the consequences.
