No parking in Falmer due to football match so for 28/29 bus - alight at Falmer Station stop and take path through to bollards to meet leader.  If taking 25 bus - alight at Sussex House stop - go uphill to T junction, turn right and meet leader at bollards.   Aim to start walk at 10.15 am.  The walk will finish at Lewes Prison but there is a pub nearby and sandwich bar.  Obviously there is an uphill section to get to Blackcap.
