RE: Average opening week temps
It can be in the 80' (I've seen it hotter) in the daytime and freezing at night. It snowed the first week last year (Unit 141), of course it doesn't stay on the ground long. If memory serves me right my sleeping bag is rated around 20 degrees and I have never got cold, even the last week of the season when it snowed or rained 6 out of 7 days and I stayed in a small cheap tent. I carry an extra blanket or two in addition to the sleeping bag.
