Mark, thank you for getting this arranged and thank you for expressing thanks to the Rangers for their service to the public. While I know the cost of a combination lock will be small, I am more than happy to pick up the costs and reimburse the Rangers or if they have a specific lock in mind, acquiring the lock and having it sent to them.
I did end up at Coe again on Saturday night, pulled out around 4am. The moon was 44% and in the west to wnw skies and did not impact the imaging at all. The moon was an incredible shade of only what I can call a mix of red/orange/pink hues. I was able to grab photons from M101, M16 and and started on a mosaic of Rho Ophiuchi. I parked in the same spot as last weekend in the lot below the visitors center. Had the spot all to myself until ~11:30 when 3 cars showed up with a number of young adults who popped up to talk, and drink beer. They did have designated drivers. A few of them came over and asked what I was imaging and e spent an hour or so just talking about everything overhead, shared a number of images I have out on flickr just to increase the understanding of our passion. They finally rolled out about 1am. Temps never dropped much below 57, and the wind (5-8mph) died off by midnight.
