Grand Canyon

From what I've seen, they don't know far ahead of time, exactly when the North Rim opens. It's basically when the snow melts and the road becomes passable. I sent a message to the park, asking for more details. They told me to check back in April, for better details, but that it's usually open by May 15th. I sent another message asking further questions, and the response was a terse, "The gates to the North Rim will be locked until May 15th."

Okay, That settles that.
