I can only agree with GC, Molly and I too have enjoyed the Cossack Owners Club Rally at the Three Magpies in the past and we will be camping there on the 23rd August, staying until AM Monday 25th August.
It is, as has been said before, a good campsite with Toilets, Showers and Water etc. The Pub does a first class meal if that is what you want and a good range of beers. The drawback is that the nearest village shop for those bits that you forgot is a good 3 to 4 miles away at least. We will attempt to carry all that we need to the site initially, at least the alcohol supply is catered for, so leaving room for more milk, bread, sausages etc. It would be good to see other Thumper Club people there during this period.
I know the Stalwart generally heads in the same direction but turns North at motorway junction 17 to Kemble Airfield, not South to Melksham and on to Sell's Green, perhaps this year he too will head South.
