It's all relative to the observer. I base my mornings on ambient temperature. I think we should pick the time once we know the weather forecast. I don't like riding up in the mountains much under 65-70F. You should invite your teacher friend who came up ACH with us a while back.What's considered early? I was thinking 9. Is that considered late out there? Also, since it sounds like you chaps have done it before, you should probably lead up since you know it.
