Piney Woods Dark Sky Retreat

Pledge Drive

We are collecting pledges to complete the road around the telescope field at the dark sky site. This is the most requested project by members that have used the site and will provide more locations for RVs, camper vans, and for members to park their vehicle around the field. We need to collect $8,500 in pledges to launch the project and get it completed for the 2026 observing season.
