Same road, miles from home 50 years later

I used to live in Kent. Paternal grandmother lived in Barnet, Uncle (mother's brother) lived in Buckhurst Hill. We would visit granny once a year, usually in spring, and when we did, we would make a trip to see uncle for an hour or so, taking us through Enfield and Ponders End. We (I, wife and family) now live in wales (different houses but within 5 miles of each other). Younger daughter has married someone whose granddad lives in Edmonton. I promised to take grandson on a train trip round london. While they were staying with granddad, I came up independently by train. They picked me up from Travellodge to go to eat at a hungry horse pub. Road report said that direct route was jammed, so we went north and then east, and I suddenly realised that we were on the same road I had used so often 50 years before, saying that we would soon be going over the bridge that replaced the Ponders End level crossing. And we did, and stayed on the road for several miles. Seems strange how many things had to come together to make this coincidence.
