You think Metlife sucks? Here's a quick-read nugget about the Vikings stadium:
Years before construction began on the stadium, local, state and national conservation groups - including the Minnesota Department of Natural Resources and the Audubon Society - requested a "bird-friendly" design of the stadium's exterior using slightly less transparent bird-safe glass. Designers, the Vikings and the NFL ignored the advice and instead used highly reflective glass for aesthetic reasons. The reflective glass, combined with the stadium lying along the Mississippi Flyway migration route, has resulted in a large number of bird deaths, double than any other building in Minneapolis. A "bird fatality study" being financed by the Vikings and the Minnesota Sports Facilities Authority was expected to be completed in 2019. If changes are made, it will now cost about $10 million to replace the existing glass with bird-safe glass rather than the $1 million it would have added to the original construction.
