Hey, I liked that sand idea....

I'm sorry you no longer have them.

I have a good friend who travels to religious sites all over the world. At each location she takes some soil and puts them in a vial then labels them. I couldn't guess how many she has but it's a LOT. She brought me a couple from 2 of her trips, (after I learned that she did this and asked about it), and they are sitting a shelf about 10' away from where I'm typing this reply.
