Oops. Did it again. Had the postcard picked and inserted into the blog, then totally forgot to write and post it.
In any case. Here is the beach at Tulum in Mexico. If you look past the ruins and down the beach, you'll see a narrow strip of beach. That beach has got to be among the best beaches in the world - the sand, the color of the water, the lack of people (although the numbers of people increase every year).
I'd like to be there now.
