It's historical
For its own fans, sure, for another team's fans. Why?
Tons of old retired stadiums out there that mean nothing to fans from other cities.
Our family has amazing memories of the municipal stadium in CLE and even bought old seats from it, but I don't think that means anything to fans from other cities.
Municipal had seating for 78,000 (Oakland Coliseum has 63k)... Much larger than others in that time period. I don't see anyone upset they didn't get to see it
