First of all, bows are not subject to weapons law in Europe, they are consider sport equipment. I travel alot with my bow in Europe and in airport to go back home in Canada and never had any problems. The only thing, they just need to be in a case when in cars or in the train. I find it funny too that the best country to shoot 3D is the country where bowhunting is illegal. I think that help to compensated to play wanna be
You can check this site for info :
www.parcourstest.eu. Up the page, you can change the language if you don't speak German. I don't know if you want absolutely to shoot a competition or just shoot a parcours, but the European have alot of them. Austria with Waidring is a really good place to go, because within 45 min drive, you can shoot 30 differents parcours. Hope that help you.
