If you are ever near Tulsa, Oklahoma, anywhere near Tulsa, the trip to Tulsa Botanic Gardens is worth the trip.  Even the drive to this remote location, north-west of Tulsa, is beautiful with it’s rolling hills and trees.  The garden is absolutely gorgeous.   Wear sunscreen, because you may want to stay all day.  Wear inset repellent, because you probably will want to take the 1.5 mile nature hike.
