I have always felt that the Grannoms on Penns Creek come slightly before the Hendricksons and that they overlap and the Hendricksons last longer. What is your experience, specifically on Penns Creek?
Wow, this must have been a completely stupid useless question or nobody has any experience that they want to share?!
It just seems like increasingly, for Penns Creek, I am seeing reports of Hendricksons significantly before Grannoms. I conclude that the Hendricksons start before the Grannoms but then often overlap and extend beyond.
