I was about to post Pathfinder #4 when I noticed I hadn't yet gotten to #3. I guess that means I have a buffer of unposted puzzles again?
ETA (6/30): There was an error in the grid; there is no entry #27. I have corrected the error and uploaded a new file. Thanks to sueonview for catching the error.
ETA (7/2): There was an error in the clues; the entry labelled 18W should instead go south. I have corrected the error and uploaded new files. Thanks to sueonview and Anonymous for catching the error.
