Surely having BBC insurance number displayed on your buggy should be good enough, if you start a club what happens to people who only use Brancaster a few times a year, or just visiting for 1 day, it places a lot of restrictions on everyone. it will be a lot of hassle for the guys organising it and like someone as already pointed out the club will get in trouble for non members breaking the rules. Self policing the beach by responsible BBC members should be good enough, how many times do you see people using the beach near the golf club, instead of ignoring it other users need to make them aware of the restrictions and point then in the right direction. Not everone who visits Brancaster to buggy know that there are restrictions in place
