Stadiums older than the Ralph that still stand have had mucho makeovers...
Like, Lambeau and Soldier
Sadly, The Ralph is in need of a major overhaul.
I was there during the KC game this season and noticed some minor and major flaws. The cinder block walls around the south end are shifting and the upper decks are forming cracks--of which have been patched.
I love The Ralph, but it's upkeep is the proposed $200 mill+...but, that's just to apply minor fixes...
Sadly, again I say I love The Ralph...it's going to be cost taxpayers at least double that for upkeep in 10 years. Investing in a new stadium would change that.
