The southern groups annual super-soaker shoot out at Winspit quarry (used for filming episodes of both Blakes 7 and Dr Who), will be on Saturday the 1st of September.

We meet up at Wareham station (which has plenty of car-parking space and also allows people to arrive by rail) at 12 o'clock and travel in as few cars as possible to Worth Matravers (where there is limited parking space). From there, it's around 20 mins walk to the quarry, so you need sensible footwear.

You need to bring a supersoaker (or waterpistol), a water container to carry water from the car park (remember, you have to carry your ammunition for that 20 min walk, so a backpack or shoulder bag can come in handy), a dry t-shirt to change into if you get soaked, and a pack lunch.

Dark clothing is recommended as there are caves that go far enough back to make good ambush points in the dark and a day-glo shirt will get you spotted quickly by fans whose eyes are already adjusted to the dark. We just love people who have white shirts with optical brighteners - they make great targets!

All are welcome, but it helps greatly if you let me know in advance so that we don't leave Wareham without anyone.

We've been doing this for years now - it's great fun and the sun nearly always shines. It's also beautiful countryside and well worth it for the fantastic view over the sea.
