Hmm. So they would, Sally. An excellent point, well made.
However, the beaver dam building / jump dismantling would only delay the event, but not render it a pointless exercise at all, on the contrary, people who find collies rounding up Indian Runners interesting would surely find this riveting. I shall write to my local MP immediately insisting that The West Fife Beaver Trials are instigated forthwith, and if I see children wearing blue jumpers and neckies there will be a Letter Of Complaint. Willie Rennie, watch this space.
