Chichen Itza

The Mayan ruins at Chichen Itza, in the Yucatan. Quite impressive, I
thought. They had a rather strange value for life, though. There was a
"stadium" among the ruins here where some form of ancient game was played -
the rings through which the ball was to pass are still visible. The winners
of said game were sacrificed. The tour guide was telling us how great this
was - though I'm afraid I'm still a skeptic.
