I noticed on the Lazy Arrow Adventures website that they have tent and RV camping available. This facility is 25 miles east of Santa Margarita on CA-58 so there should be very little light pollution from nearby towns. If you like to camp and view the stars through your telescope, this might be a nice, safe place to do both. Go to their website and look under “Concerts”. Click on the images above to see them full size.
