My guess is that some members of the group are not supportive of some of the issues raised in the petition. Perhaps, for example, some folk don't want Hoveton Great Broad opened to the masses. Perfectly valid concern but perhaps the petition is suggesting that rather than closing waters the BA should actually be opening them up, something that I agree with. Had the petition stuck to the core subject then perhaps the number would be higher. On the other hand the petition writer has chosen to take this opportunity to raise a number of issues, quite understandably. Whatever, the writer has got of his/her nether regions and done something positive rather than just sitting on the sidelines, nitpicking, point scoring and trying to undo the good work of others.
