... and don't anymore.
I'd better specify what I mean by that: I'm not talking about curved bats, underarm bowling, gentlemen playing in three-cornered hats, or members of the gentry putting 100 guineas on their team to win. I meant more stuff which (some of) you might remember from 20-30 years ago, to whit:
Unhelmeted close-in fielders
Umpires in big coats
Domestic competitions sponsored by cigarette companies
Counties playing at six or seven different venues in a season
Limited-overs games played in whites (and ODIs referred to as 'one day Tests' by commentators)
Please feel free to add your own.
