I did get an email response from her and a link that I'd like to share:
"Thank you for my lovely magnet!!! - it is Great!!!...a wise little owl to guide me on my way. :)
I was in my dorm the other day and Issac popped his head around the corner!! :) It was such a nice surprise and an even bigger surprise to receive a present from you through him. I think your magnets are great and I think the whole project is Great. It's big. A really magic idea.
Here are the details of Las Pozas, the sculpture park built by Edward James, near the town of Xilitla (it is in the very south of San Luis Potosi). Primera Plus busses go to Xilitla - you can check on their website where from - http://www.primeraplus.com/. Here is a website with more info http://www.xilitla.org/.

Cenotes are amazing Mexican caves filled with turquoise water, that have vines growing down often through an opening in the roof, that the sun steams in through. You can swim in them, and they look like this. They are all over Mexico (mostly in the south I think) and they are magical to be in."
Aprylle is British but would like to settle in Mexico City and the above are some of the places she has visited. I haven't a clue where she or the magnet will end up but, for now, I will tag it in Mexico.
