According to several people I met today at Salbris, I was wise/lucky to have decided not to come to the site on the official preregistration day. Apparently the traffic jam peaked at 18 km long, and some people waited in staging filds for up to 7 hours. I can not imagine what that must have been like.
On the other hand, this morning, I had about a 20 minute traffic jam and registration delay.
I guess it is safe to say that the organizers were a little overwhelmed yesterday, but had recovered well today
