Re-organizing Folders and Collections in Adobe Lightroom.

I've taken advantage of this weekends Northeaster by catching up on a must needed re-organization of my Lightroom folders.  My IMac is low on space and as a solution, I am moving my images to an external drive.  In preparation for the move, I've created a new folder system involving yy/mm/dd and am refining my metadata by editing keywords and creating sub-keywords.

Needless to say, I am ready to get back to the business of shooting photos.  I do acknowledge that this is the necessary evil of digital photography.  Remember those days of hours in the darkroom with caustic fumes?  Now that was evil!
