i came home from work today as my dd 18 in sat in the the kitchen while i made dinner she said "dad told me the pines cones are talking" what i said she said go out and listen the pines cones are popping open .. so i listened and i did hear a cracking noise .. soooo i had to google it and sure enough my dh is not crazy ... the do pop and crack when they open ... hmm he is so full of surprises even after 23 years .. so if you have pines trees and it is dry take a listen and you will hear them too!!!
