Longwood Gardens. We like to feel as if all of our travel experiences are wonderful, even though some travel days are less than successful, but every now and then we’ll find ourselves somewhere extraordinary.  It’s such a surprise when it happens. With an estimated 1.5 million visitors per year, Longwood Gardens in Kennett, Pennsylvania is one of those extraordinary surprises.  We knew our visit to the gardens would be wonderful, but the surprise came in the fact that we spent nine hours exploring the gardens and we left plotting our return.  Leaving when you want more, is always the best time to leave.
