Description
I will present recent and new results from our studies of kinematical and chemical structures in the solar neighbourhood. I will particularly bring up the Hercules stream and discuss its propoerties and what they might tell us about its origin. I will also discuss our attempts to trace the Galactic thick disk to its highest metallicitities, where it possibly ends, how it relates to the thin disk, and what it means for the origin and evolution of the two disks.
