I think these Pit Stop pairs were also pretty close?
Shanghai, TAR 6 and 16, 1.04km
Prague, TAR 15, 1.08km
Hong Kong, TAR 2 and 17, 1.33km
Seoul, TAR 4 and 17, 1.33km
St Petersburg, TAR 17, 1.53km
Interesting note: Tiantan Park is slightly off the Beijing meridial axis, but if you go from south to north in a straight line you can go through where Kevin/Drew were eliminated, then where Bilal/Sa'eed were eliminated, then the faux Pit Stop in TAR 14, and finally where LaKisha/Jennifer were eliminated...
