Never been to the Ypres rally, probably going with a friend who has never been to Ypres rally neither but has seen WRC in Portugal and Catalunya. So we both lacking a profound stage knowledge of Ypres rally. But YouTube video are always good for online recce to find the most interesting places. Here is a very good one from last year. I guess the complete video is from the Kemmelberg stage? Especially the s-sweeping corners on 0:10 and the T-junction at 2:00 are hotpoints
