Just had a scan through all the results. Bit of an eye opener to see the biggest starting grid was HF1! (Ignoring, for the sake of clarity, the Dutch entries in other races.)
The first Masters meeting at Imola last year was not well supported either, and that was a month later than this one, so maybe it’s just too early for some UK based folk to be trapesing across Europe?
Off topic, but- Interesting that at Barcelona this weekend, the 60s Endurance has ‘only’ 44 cars entered, whereas CER1 has 50. That’s not the normal way round....
