Trip to Sag A is definately worth it...stars are so tightly packed, ye could explore with a 1 ly range. Theres even an achievement fer it I think.
As bingo points out, unless ye go somewhat off the main 'motorway', then it is literally a highway/motorway...just put the boot down and grind the distance while struggling to stay awake. Id suggest the neutron highway to anyone practiced in surfing the neutron waves, but if its a virgin experience, I recommend getting to jacques first...neutron surfing can be hazardous to ones health [big grin]
Take care in the black cmdr and keep er lit ^
