I myself am in Vancouver CA area, so I can appreciate the grey boring skies as they try to decide if they'll rain more or not. I usually find these grey days the best to escape into the deeper woods and shoot waterfalls and streams. That, or I practice my closeup macro shots of plants while the sky acts as a giant softbox. Shots like this little mushroom are usually what I get on these grey sky days
