HELP! - Need advice planning trip to le Tour, Stages 14 & 15

I am planning at trip to see le Tour this summer. My goal is to be there for two of the
mountain stages:

Stage 14, july 20, 2003 Saint-Girons - Loudenvielle 191,5 km

and

Stage 15, july 21, 2003 Bagnères-de-Bigorre - Luz-Ardiden 159,5 km
http://www.letour.com/2003/presentationus/difficultes_06.html

I am planning on flying into Barcelona on July 19 and renting a car. If you've been before and have
advice/suggestions as to: When do they close the roads? What the best way to approach this? Anything
I might forget about? Parking on these roads? How early should I get there?

Thanks in advance, Lenny
