It was quieter than other years at BN, also saw a few empty spaces up there. We drove through Maison Blanche by bike on Friday, and it seemed also much quieter than other years.
At the track on Saturday, I felt it was really busy, altough I still saw some empty spots on the grandstands opposite the pits (I was sitting on grandstand above it). From Dunlop to Tertre Rouge, it was very crowded on Saturday, looked like more people than in the past years. When I got to the inside of Tertre Rouge around midnight, it was still very busy up untill 2 am. During the night and on Sunday it was calmer though.
