Update, October 13, 2009.

The weather still does not cooperate. Have not seen the sun (except for a couple minutes) the past 5 days or so. Cold and snow flurries each day. Calgary had an overnight low of -16C (a new record) over the weekend. Perry was able to finish sealing off the screw heads on the underside of the four sections by heating up each screw head with a heat gun and then applying the sealant. He says now he is totally done the bottom. The weather is to get much better this weekend, but I have a 2 day fossil turtle conference to attend at our museum during that time. The plan now is to leave the conference immediately after it ends late Sunday afternoon and do the flip then while it is still light (and hopefully warm).
