Blue sky ... blue train

It was a crisp clear day with wintry sun failing to thaw the puddles on our walk. The roads were busy, for a lockdown, as was the frequency of trains on the mainline. Who was travelling was hard to see but their journeys would have to be essential under current rules. The buses into East Lothian all had one passenger each but when our walk brought us to the promenade it was so crowded that we came home by a quieter route.
