tours of White House gardens?
 

We will be in Washington in October and are arranging to tour the White House. I know that there are specific dates for tours of the gardens earlier but is there anyway to see the gardens in October?

Too bad Clinton is not still in ofc.

why?

If Clinton were in office, a person might still be able to arrange a private tour, after the September 17 closing date.

The garden tours are only offered a few days each year. The White House website (whitehouse.gov) has the details.
I don't imagine you'll find a more authoritative source than that.
