 Today, the modern Putty Road between the cities of Windsor and Singleton follows Howe's exact path and is a major thoroughfare for wine tourists coming into the Hunter Valley from Sydney.As previous plantings in the coastal areas around Sydney succumbed to the humidity and wetness, and plantings to the west were limited by spring frost damage, northern reaches leading to the Hunter became, almost by default, the wine region of the new colony.The first major planting in the Hunter Valley came in 1825 when James Busby, widely considered the father of Australian wine, purchased vineyard land between the settlements of Branxton and Singleton and named it Kirkton after his Scottish birthplace near Edinburgh.
