Started yesterday on the 10th of January, Slowball Test Trip. We'll be on the road for 4 days and visit 5 countries. The answer for the last hind is Gdansk. Yes... the destination for Slowball - Art on Wheels '19 Expedition will be Gdansk, Poland. For the next one, take a good look at the picture.
Watch out for the Slowball stickers and hashtags in social media.
