Amarillo and Palo Duro Canyon (or may be not...)

This is the article where I am supposed to tell you about the 9 hour bus trip, in order to reach Amarillo, in the north west corner of Texas, the cattle auction that I was supposed to attend in the morning, and the hike planned in Palo Duro Canyon.
But.... a few minutes after calling the passengers for boarding, at 23:45, Greyhound announced that the bus would be at least 4 hours late. By the time I get to Amarillo, jump into a taxi, reach the Airport, do the paper work in order to get the rental car, and reach the canyon, it would have been at 2pm, may be later.
So instead of waiting 4 hours at the Dallas bus station (believe me, this is not something you want to do...), spending the night and morning in the bus, having a quick look at the canyon, flying to Austin on the following day, taking a taxi to the bus station, and then heading to San Antonio, change of plans: at 1am, I headed back to the hostel from which I had just checked out, and will spent 36 hours more in Dallas.

Bad luck, Palo Duro really seems spectacular, from what I could see on Internet:
