Thanks for the clear explanation. I took part in the Round Britain Rally in the UK a few times and then we started to organize a similar style landmark rally with the Dutch Moto Guzzi Club. It sound very much as you describe the Texas Grand Tour.
Our objective was a rally that could not be finished and it was all over the European continent from Poland to Spain, the Alps and of course Italy (and the countries in between). 150 Landmarks, and still there is always someone who visited all places. However, in 2005, before Google maps and Google Earth, it was never completely finished by one of the competitors. 2025 is the next Landmark Rally of the MGCN.
