Importing folders and subfolders?

[gchappel]

As I put my toe in the retirement waters, I am looking back through older works.
I started using lightroom in 2009- and the catalog and metadata search functions have been terrific for my searches.
I have 10,000++ images from before 2009.  These are all in dated folders- a separate master folder for each year, and under that a separate folder for each shoot date.  I would like to import all these images into a new catalog- so I can do metadata searches. 
Is there an easy way to import these in bulk, or do I have to open hundreds, possibly a thousand or more, individual dated folders to import the images? 
I tried google searches with no luck- any ideas here?
Thanks in advance.

See the section: Importing your existing photo library.

Does this help?

Just open the normal import window select the root directory of your file structure, make sure include sub-folders is clicked and import at current location.  Find something else to do while Lightroom builds thousands of pre-views.

Thanks!!
That did it, I did not see the include subfolder option.
