Vienna > Saltzburg> Sandviken Sweden > Kouvola, Finland > Lipno, Czech Republic, 3,202 miles calculated by Yahoo Maps... or to put it into a North American frame of reference... it's about the same as driving from KEY WEST FLORIDA TO SEATTLE WASHINGTON, ... before the regatta decision is made...
It's only 1700 km between sites... just about 1,050 miles between Site A, Lipno, Czech Rep. > Sanviken, Sweden... with another option in Finland...
