Sounds like you have the bases covered there Tengu and we could dig one of the boxes into the ground like a kind of makeshift fridge that should serve well for the weekend grub. I will freeze some poly bags of water for my cool box so i don't think we will need much more than that - Just a word of warning to the hammock campers among us - Mark (Lupus) mentioned a nearby lake and we are now entering the mossie season so make sure you pack your netsIve sorted out 3 lidded polysterene cases and about 35 ice packs of which I hope to freeze half.
(could probably freeze more but Id worry they would freeze together in transit)
do we need any more cooler boxes? I dont have a picnic one, but I assume you will have some of your own I can supply ice packs for
(could bring more packs if needed)
