Dog walkers and people with kids is just life and quite nice to be around . In London they take them out for a trip in the carSometimes it is...but on the nice days, it's full of dog walkers and families with young children.
I have an 8 year old, so know all about the latter, but it doesn't help cyclists much.
Glynneath, on the other hand, was perfect for us today. None of the above, and amazing views from the top of the mountain, with snow in places, despite no sign of it where I live.
