Depending on membership take up and crowd limitations I'm not sure pay at the gate will be available for non members, Leeds Exile.
For example if Essex are limited to 1,500 spectators for home games and the membership is 3,000, although not everyone will wish to attend on a given day, say 1,800 members wished to attend there would have to be a lottery system, to choose the attendees. Therefore no room for pay at the gate.
I expect a similar arrangement at Yorkshire, although the grounds, and membership are larger.
However, all this could be wishful thinking if yet another new variant is set upon us.
