Good to know about the sticker! And that border hopping with a rental between those two countries shouldn't be an issue. As for trains, nothing against them, but for this part of the trip, the perfesser wants a shot at driving a nice German car on the autobahn and we can work the budget ot make that happen for him

He's actually liking that idea so much that he's game to loop back around to Munich instead of ending in Salzburg in the name of better long haul train options.
