Was at PR last weekend for the ELMS.
Work has started on fencing around the track, also on Mistral straight. A new footbridge has already been built from the paddock area to the outside of Mistral straight near the chicane. Parking at the back of the paddock has been resurfaced and will be covered apparently.
With al the new fences going up, PR is just another beautiful track that will be ruined by F1 (at least for us photographers).
I still can't get it how they will cope with all the in- & outgoing traffic during F1 weekends. There's literally just one road in & out the track, guess the easiest way will be to fly in. Spotted a few small campsites near the track, but that won't be sufficient for the F1 crowd. If you ask me, F1 will be pure chaos down there > no way to get in, no way to get out, even more overrated hotelprices than now ...
