Sad little fact: With Zhuhai now gone there are only 3 non-FIA Grade 1 circuits left in ACO sanctioned series: Circuit de la Sarthe (Grade 2), Estoril (Grade 2+1T), Inje (Grade 2)
In USCC only one is Grade 1 (does the "new" modified Indy have Grade 1 yet? if so then two) but that's not ACO territory anymore
edit - apparently Estoril is now 1

So only Le Mans and Inje...
