to answer someone's query , for valencia you could buy tickets in advance at bankcaja , or at el cortes ingles , a national department store
but it is no problem to just buy at the gate as most people do
and is it worth it ? you bet ya!
you will learn more than at any grand prix because there is time to watch every individual driver for 10+ laps each day
with regard to the time sheets posted here , remember that , in round figures , the track got faster by a second a day as the temperatures went up and the rubber went down ; so if other factors were equal [ am sure they were not ] the list would go
and massa and koba were really trying [ puffs of gravel ] but hamilton was just running smooth laps
frankly , the way the track went , ~I expected a couple of drivers to drop into the high 10's late on day 3
