Not bad as the Truro web site gives the total attendance at the game as 279 and my friends that were there said that there was about 20 Dover Fans, with 15 of those that traveled on the plane with the team. Good old Radio 5
This Truro video of the game may give you a true idea of the crowd and while Dover did well they never had it all their own way.
The video does start off with an old game then goes to Tuesday night..
