  If we want to understand the evolution from star clusters to the Galactic
field star population, the Solar neighbourhood is an ideal place to start. It
contains objects from dense, very young clusters to old and almost dissolved
moving groups. I describe the observational evidence for the ongoing
dissolution of OB associations and open clusters. Subsequently, the
interpretation of the local phase space distribution of stars in terms of old
moving groups is discussed, emphasising the present limitations. Finally, I
discuss future observational requirements and the possibilities offered by
upcoming astrometric space missions.
