We want to take out dead trees and trees blocking the southern view, complete gravel drive around the telescope field with pullouts for vehicles, put in a shower, finish the remodel on "The Lodge", add potable water, setup tents for shade, install surveillance and an AllSky camera, add a couple of simple pads for telescopes, and finish building out and installing the solar battery bank and Starlink. Get your tax deductible donation in before the end of the year!
