For several years, in the 1960's, Good Friday was the start of the Aldermarston March, which lasted to the Monday.
Our YCND group, in Hackney, would meet up with our sleeping bags, etc. to get the arranged coach (we always had a large contigent), to the starting point. One year, the march was split into two, with all of us in the East starting off in Essex.
There was incredible arrangements for these marches, with all groups being given colours and numbers. We slept overnight in schools, churches, village halls, large tents, etc. etc. All the sleeping bags and any luggage bags were loaded on lorries (ensuring all were carefully labelled with colour and number to identify them), and these were off loaded at the town we were overnighting in.
Still think back so happily to those wonderful days when I was young and still believed that the future (assuming we were not all blown up), would be better than the present. So glad I did not have the gift of foresight to see ahead to the sad times now.
