My youngest sister, Allie, is enjoying that brief period between graduating from college and entering the working world (she has a job lined up that starts soon). Like so many young people these days, she's passing this time by... going on a cruise with my mom.

Here's a picture Mom sent of their tour of Tulum, a Mexican ruin that Sarah and I actually visited last year when we took a relaxing Mexican vacation. At that time I wrote on my blog, "[Tulum] was really beautiful and I'd love to say that Sarah and I learned a lot about ancient Mayan culture, but honestly, we mostly took wacky pictures of ourselves, many of them involving Sarah punching nature."

Allie and Mom, though, were maybe smarter tourists, and took the guided tour.

Mom: [via e-mail] Carlos was our guide and he gave a great deal of info about the Mayans. We couldn't go inside any of the ruins. There was a red handprint on one building where the hands had 6 fingers! This was someone of royalty and Carlos thought it was because of all the family marriages.
