Took the early buquebus accross the river to Colonia, Uruaguay and then headed up river via Dolores and Mercedes before a final crossing into Argentina at Gualeguaychu.
My goal was to confuse the Aduana into letting me into the country again with the moto; it worked.
I've another 8 month extension but alas the moto is sold so the entire trip was just to facilitate the sale in BsAs vs Uraguay.
Met amigos for lunch in Gualeguaychu and then rode the few hours back into the Buenos Aires.
