Sorry I couldn't find a circuit challenge thread. But, I can't figure out which circuit the photo at the below link was taken at. It could've even been at a testing circuit too? Just click on the image in the center of the top row, it's the Life Racing L190 driven by Giocomelli http://www.tumblr.com/tagged/bruno%20giacomelli
I think I can rule out most of the circuits from that year. Namely: R1-Phoenix, R2-Interlagos, R4-Monaco, R5-Gilles Villeneuve, R6-Hermanos Rodriguez, R7-Paul Ricard, R8-Silverstone, R9-Hockenheim, R10-Hungaroring, R13-Estoril, R14-Jerez, R15-Sazuka, R16-Adelaide.
That leaves R3-Imola, R11-Spa, or R12 Monza as candidates... I think. I just can't place the turn or chicane he seems to be approaching. This is bugging me. Thanks.
