Back out to the national park this morning, passing Mars, Earth, Venus and Mercury on the way:
https://www.visitnsw.com/destinations/country-nsw/... (but we couldn't go right into Siding Spring Observatory itself).
From Camp Blackman which was the HH site for the 2006 WRC and where I'd decided we wouldn't camp this time because a campground with 100+ sites is not Geoff's idea of a good time, I ran a 5ish-km loop on the firetrails around the river flats with no shade and head high grasses on either side of the tracks, although being right in the basin of the old volcano did mean having 360-degree views of all the surrounding peaks and the observatory on high in the distance. This run would have earned me an entire 30 points during the WRC.
Afterwards I'd thought about walking up/around Belougery Split Rock but didn't want to do the rough trail without a buddy so settled for a 3km creek walk which G decided was too much for him anyway, then we drove out the western end of the national park and beyond the end of the ranges saw the signs pointing to Emu Logic which emu farm I remembered as having hosted one of the Detours on last year's Australian version of The Amazing Race. So we looked in there but it was pretty underwhelming, then drove north in a hot car on dirt roads to Baradine and the Pilliga Forest Discovery Centre (to get some ideas for tomorrow's touring) before heading back to Coona, as the locals call it!
