Mix together in a bowl, brown sugar, maple syrup, bourbon, salt, butter. Add chopped pecans to the bottom of the pie crust. Top the chopped pecans with the crispy bacon pieces. Then pour the syrup mixture, very carefully, over the nuts & bacon. Then use the whole pecans decoratively around the edge of the pie.
Bake in a 350 degree preheated oven for approximately 45 minutes. You can shake the pie a little to test for doneness or the knife method.
