How ? There have only been 3-4k empty seats at our last couple of home games in the championship and will be less after 1/1 when the half-season ticket lot turn up. With prem opponents taking full allocation, tourists wouldn't get much of a look in.
It takes less than an hour to get back to mid Sussex (on the trains we pay for as part of the ticket price) leaving after the final whistle, but don't let the facts bother you.
