I have walked my dog, off leash, for many years on the old railway track to the Westcan terminal.
The trail runs through an industrial area and has been used for many years by local walkers and dog owners.
The CERCA has recently carried out an excellent upgrading of the track and named it Cowichan Estuary Nature Trail.
The noise created by the mill does not disturb the birds in the area, neither does the truck traffic travelling on the road to the terminal, that runs parallel to the trail.
During the hunting season (October to February) I am sure that the birds are more likely to be disturbed by the gunfire from the estuary, rather than from a few dogs that are enjoying a walk with their owners.
