My sister's house apparently, which looks to be just about smack underneath a few miles SW of Diss. She would like to know what time to set up her sun lounger!
For the main event, I thought I might head up to Putney and watch from the riverside, which is about 4nm WSW of Buck House - I assume the main formations will continue on course for several miles before turning towards their dispersal areas. Then I'll go and enjoy a pint in the Bricklayers.
