Our church had a tradition of holding sunrise (Son Rise) services at a pavilion overlooking a lake. The service was lead by the Senior High Fellowship group. My Senior year of high school, I gave the sermon. I remember how scared I was, but I had taken a public speaking class at school and managed to "fake it, until you make it."
Afterwards, I realized that I had never gone to any other sunrise services before that one. I'm the oldest of 7 children and I think it was too much for my mother to even consider. I'm glad I have that memory.
