A pretty big moment for me to cross the border across the Danube. Had heard of a Bulgarian “ecological tax” at 10 euro which everybody is supposed to pay, but to us there was only laughter, smile, thumps-up, and a pair of gaping looks from the frontier guards when they heard about our long biking trip.
