The cache is not at the published co-ordinates.
The published co-ordinates take you to what was the centre spot at Christie Park, former home of Morecambe FC. Now a supermarket car park, a small plaque is all that informs visitors what used to stand here. On the plaque, you will find the year it opened (ABCD) and the year it closed (EFGH). Alternatively, a small bit of internet research will tell you the answers.
Final location is at
N : 54 (F)(C+E).(A)(B-D)(B-E)Â
W: 2 (C+E+G)(H).(B-E)(C+E+G)(A+C)
