Emerald - Acheron River What do you do on MotoGP race day when everyone else is at the island..? Go riding! Setting out - Macclesfield Rd. Warburton Hwy, heading for the hills.. The Yarra river at Warburton. Stopped at the bakery for coffee and cake. The road to Mt Donna Buang. The Acheron Way. The first of the debris on the roads that we would encounter today.. Happy to be out and about. Crossing the Acheron river for the first time. Distances. Back on the asphalt for a while. Crossing the Acheron river again at the Fieglin Rd turnoff.
