Last week's meta asked you for an alliterative phrase. The four theme entries (TEOTIHUACAN, SALAMANCA, JAMESCAAN, MAJORARCANA) all ended with various permutations of the letters NCAA. There are actually a bunch of alliterative phrases associated with the NCAA, but the most appropriate one is Final Four, since NCAA are the final four letters of each theme entry. (I also took Sweet Sixteen, since there are four sets of four letters in total.)
No meta this week, just a good old-fashioned themed puzzle (pdf, puz, pdf solution). Enjoy!
