Whistle while you work

Dear Editor:

Five days a week, I hike on different parts of the Pipe Dream trail system. The series of recent “storm bombs” seriously damaged some sections. I want to thank the folks who have been repairing these trails, most (all?) of whom are volunteers. I have to confess: When I hike across a repaired section, I see the Seven Dwarfs with their picks and shovels, whistling while they work. Thanks.
