Migrating Cranes

When I got off the bus, I could hear the cranes but I couldn't see them (my glasses had steamed up).  The sky is quite large, so the chances of finding the cranes were quite small (and would have been much smaller if I'd taken my glasses off).

A stressful day.  I'll not go into details.

The cranes though are flying through.  I'll blip them every chance I get.
