I was thinking, with corp spying etc would all the major sports stadiums be enclosed in the future or would they still have some that are 'old fashioned?"
In RL right now, forexample the areas like Dallas, Tampa Bay, Seattle. Milwaukee and New Orleans have domes. New England, Boston, NYC, Baltimore and Philly are all open to the elements. a 2 hour rain delay in Philly as that city heads for it's second World serries Championship, a foot ball game in a blizzard in Foxbourough are all part of sports lore.
Would purists keep stadiums open in the future- remember the Astrodome originally had a live grass floor- or would they all be enclosed because of the environment and non-network spies?
