This is the third time this week (Wednesday, Saturday and Sunday) that ESTONIA has appeared as the answer to a puzzle clue!

Fun puzzle - and everything fit together so perfectly! I quickly filled in OLD FAITHFUL and CRATER LAKE in the northwest quadrant, which led me to enter NATIONAL PARK for 69A. But once I encountered NIAGARA FALLS, I knew NATIONAL PARK couldn't be right and something else was going on. Finally figured out the theme after heading southeast to the EVERGLADES and EPCOT CENTER. Mr. Siegel, you certainly made good use of your time on the subway!

A geography correction for today's Wordplay author: while there is a city of Cape May on Cape May, NJ, there is no city called Cape Ann on Cape Ann, MA. Cape Ann's city is Gloucester.
