Get out your diaries... There are still some places available on a number of PAC access events between now and the end of the season.
They include the Warping Drain (Lincs) on Saturday, February 7; Hykeham Pit (Lincs) on the weekend of February 14/15; Ecton Jigsaw Lake (Northants) on Saturday, Fenruary 21 and Saturday, March 14; and Quays Pit (Surrey) over the weekend of March 21/22.
Application slips with details of ticket prices were included in the last Pikelines.
Events organiser Mark Skinner said: "If you have lost your slips for these events, all you need to do is write your name, address on a sheet of paper include your PAC number the event you are applying for and a cheque payable to the PAC for the number of tickets required and an A5 stamped address envelope."
