Never heard of it before. Alas, the odds favor the locations being too far to go. For example, the one tomorrow is almost 30 miles as the crow flies, almost 40 by car (and even farther by bike)

Looking to check the possibility from Lin & Kermit's did point out something worth checking. Looks like there's a "whole degree" lat/long crossing (ie a "graticule corner") near them (N47° W124°). That'd be someplace to visit. :-)
