We really enjoyed looking out for the planets and stopping to read about them and take a selfie. Our young one got really excited seeing them and wanting to learn about the planets. We sadly didn’t get to do all of them as we didn’t have time to head to Siding Spring observatory but hopefully one day we will be along the hway again and we will make the trip out. Our only negative was there wasn’t any signs to tell you it was coming up or part of that rest stop so we tended to have to u-turn as we would pass the rest stop and see it. Would be nice if an extra tourist sign was added to the rest stop sign maybe stating virtual solar system.
