Just confirming the route:
– depart DUX towards high st
– all the way to Albert Park
– turn left for ~2/3 lap clockwise around the lake
– exit behind MSAC for Kerferd Rd
– turn left at Beach Rd and head to Black Rk
– return to Carnegie via Bluff, Sth, Tucker rds
Early exit options at Nth, Sth Rds and the usual pre Black Rd cut throughs to Bluff.
