I love watching the sun come up at Le Mans! Get to see a sunrise twice in one day! Plus it gives me a little boost of energy . . . at ~12am EST!
Le Mans is on the bucket list along with the Isle of Man. I can't emphasize how awesome it is to attend a 24 hour endurance race. It is a true event. Watch some racing, go get something to eat. Watch some more racing, drink beers, watch more racing. Get a little sleep, wake up in the middle of the night and stay up until the sun rises. The coolest moment though is sitting around a campfire at 3AM looking up at the stars and hearing the race cars.
