In reply to john morrissey:
You can still access as per BMC RAD.
The fences have been there a long time now.
The Wilton Management group have brought this up with the club(s) several times in the past, but they're adamant about access and discouraging non-club shooting.
W2 and W4 should be accessed from the Stile erected around the corner of W4 specifically for the purpose.
It's not ideal, but it's only a 2 minute walk.
