Bookmarked that page and will try to remember to send observations from suburban Columbus, Ohio. I will definitely post observations here.
My plan as far as AM reception that day is to head out of town a little bit, maybe 5-6 miles east of me, to a rural area where there is much less man-made interference.
Guessing WLAC will be a cinch catch for me here, as its skywave signal is huge in this area pretty much every night. Judging from that map, KMOX should roll in as well. WBT will be non-directional at that point as well so it might grab some new listeners.
