A person that has been to many worlds during his travels in the export/import business has written a tongue-in-cheek guide for those people who may be wanting to travel to another world. He describes some of the conditions a traveler from Earth can encounter on a different planet. These include such things as a difference in gravity, weather, atmosphere, fauna, and flora, geology, daily and yearly cycles, and sunlight. He takes a somewhat humorous approach to his subject and doesn't show much sympathy for what he refers to as "moles" or those who have not been off world. Still it should be required reading for those planning a trip to another planetary system.
