When i was out exploring i found Joe Builder on the Hypergrid and he told me that he got some vehicles on his grid and big areas to drive them. Joe is a builder in all sense of the word. Lost world have big areas connected with the hypergrid.
I visited a wasteland. Drove a truck, killed some zombies or something. Visited like Jurassic park, a space station and a underwater world. I think there are much more but not everything is up all the time.
Joe told me he is using older Opensim and ODE and it worked good.
