The field is Painball Sports which is a bit further south than McLaren Vale so it will be a long drive for the northies.
The entry fee is $25 which includes 100 paint balls, coveralls, mask, gun, etc. As stated above, it's $20 to refill with 100 paint balls.
I'm waiting to see what sort of interest it get's but it will probably be early November unless people want to do it earlier.
