Czech. The card shows the Vltavy river. It is the longest river within Czech republic. Running southeast along the Bohemian forest and then north across Bohemia, through Cesky Krumlov, Ceske Budejovice and Prague, and finally merging with the river lake (Elbe) at Melnik. It is commonly reffered to as the Czech national river. She wrote: I used to go with friends and canoos from the damn Lipno and we ended in Cesky Krumlov or in front of Ceske Budejovice. It is kind of national hobby in July to do this. But just for a part of people, not everybody likes the discomfort and kind of danger. Maybe one day we try this with our kids.e
