I was in Escondido as well with the whole family. We also watched the depart and return [were at the Finish line at approx 150m mark (south side) in shade ;^)]
The family enjoyed being by the team buses watching interviews, meeting Bob Roll and Chris Horner (who lives in San Diego), etc.
Co-worker watched stage 2 and told me about the guys just collapsing at the end. TV reporting next said somethign like close to 40 riders (?? or some larger number) ended up going to the hospital to get IVs to rehydrate. I enjoy a 60 mile bike ride, but a 100+ mile ride at twice the speed, road temps approaching 120 degrees - no thanks.
