As a bus driver I come to Hayling Island quite regularly and go round the bends 5 times each way, this really can drive you round the twist.
The cache is not at this location, but you can find it by working out the following.
Take that N50 AB.CDE W00 FG.HIJ.
A=Justin Connor,
B=Daisy Cameron,
C=Stuart Atkin-Cameron Nugent
D=Fiona Harris,
E=Marzena Godecki,
F=Lauren Taylor,
G=Ernie Gray,
H=Natasha Jacobs-Tommy Dysart,
I=Bronson Shelton-Paul Jennings,
J=David Hunt+Brenda Waite,
All 14 numbers should add up to 56.
Don't let this drive you round the twist
