Good write up Allan, I will let you do the same for Chaffey Dam
. I will ad SQM readings. Pony Club is about 21.4, Bretti and Chaffey Dam can exceed 21.8 so are very dark. Bretti has no light domes, Chaffey Dam has a small dome to the north but has star reflections off the water which make the site appear a bit brighter.
