Things have certainly changed, my first five years were spent at Booth Lane in Middlewich, with a view across the A533 to the Canal and the Royal Venton Sanitary Ware works. That was 66-71. Of those, the one thing I'd avoid like the plague with kids is the A533! But traffic was a fraction then of what it is now, and I would have kids on the B3111 in Bath where we live (it isn't signposted) but I'd watch them like a hawk near the front door. It's traffic is probably higher than the A533 was then
I don't think the politics of "yer can bluddy well afford it" is a good way of conducting business, however, unusually I have some sympathy with BW. I enjoyed some else's EOG mooring for 2 1/2 tears, and they charged me nothing, but BW still had a boat floating on their canal over their land, and so half the going rate seemed fair, after all BW couldn't grant access to the mooring, but they could decline to permit it (something many people miss. If your EOG is on a blind bend BW may say no!), and the owner is getting benefit out of BW maintaining the waterway. An end of garden mooring on the Somerset Coal Canal has, I suspect, limited appeal
