When he told me the correct response was racetrack, I had to admit I'd never heard of it.
Never one to promote willful ignorance, Joe proposed that we swing by the town on our way back from Spa and see if we could complete a lap of the track.
We were lapping the circuit blind, using the crash barriers to guide us round what we presumed was the track. Joe had a rough outline of the classic circuit in his head, and as we powered up the main straight, approaching a blind brow, we expected to come upon a swooping right-hander. Instead, we had to slam on the brakes as we came upon a T-junction! Oops.
Turns out the circuit was modified in the 1980s for motorbike races, and we'd made a wrong turn onto the shorter course.
So we completed our high speed triangle, headed back to the start/finish straight, and tried again. This time, we found ourselves on the sort of track that even puts Spa to shame.
You can attempt an overtake between a chapel and a wall, but only if your balls are big enough. If they're not - whose are? - then how about a fast right-hander that runs up a blind hill onto the straight? Just mind the stone buildings on the corner, you wouldn't want to run into one of those.
Oh, and then there are the trees to take into account. Going off line and into the forest is never a good plan. Chimay's hey-day was pre-Armco and catch-fencing, and even the modern safety precautions are rudimentary at best.
The only Chimay Grand Prix to be given Formula 1 World Championship status was the 1954 race, won by Prince Bira, who was behind the wheel of the legendary - and beautiful - Maserati 250F.
