Mothers can sometimes suck the fun and the joy out of events because we can focus on the teensiest of important details. A man who hasn't lost his wonder and awe about life makes a great buffer.
My life would not be complete had I not experienced a dad who was unafrsid of the unknown and knew important and dangerous science and stuff!
My own kids getting filthy dirty and being used as tools/helpers have become richer human beings as well!
You dads who include your kids in your adventures...carry on. Your kids will be full of memories and possibly fodder for therapy sessions.
