yea, we left around 830am in the morning, didn't arrive at puebl

until like 11:30pm.  drove 15 hrs, 1000 miles, took breaks here and there.  but honestly, i feel like driving back is more difficult than driving to the west.  mainly b/c towards the end, i was tired both mentally and physically, but on my way to the national parks, even though i was tired physically after driving 1k miles/day, but mentally, i was still pretty enthaustic to see all the sites.
