You don't see space travellers very often. They tend to sneak fairly unnoticed. The only descriptions that exist, come from random sources and are contradictory.
Sometimes, they are being spotted in the least expected places, in the middle of crowd.
At times they can be met in cheap motels and remote gas stations.
Apparently, space travel is becoming a popular way of spending time among alien civilizations. Planet Earth seems to be becoming a dream destination.
I have collected existing reports and sketches from casual witnesses to produce images below.
