As a supporter of the the Hammers since the 80s, I have always enjoyed going to the Arena as unlike most other circuits, it actually has a bit of character.
Typical to get negative comments from idiots who think all speedway stadiums should be, in part, a dog track with the usual boring cement hole on one side and 'grand' stand on the other.
Each to their own, but I love the Arena and will miss it, all of it terribly should a closure occur.
