Anything found in a permanent location that was created as a tribute to or for entertainment as it relates to Star Trek.
Rides, shows, and other amusements that are permanent attractions would qualify whereas "Star Trek Conventions" would not due to their limited time of availability.
Permanently placed statues, displays, monuments or locations named after characters or items found in Star Trek, or homesteads/birthplaces of cast members if they are for public viewing would also fit into this category. Locations used during filming may also be submitted as long as there is verification/citation of the related usage. As long as they were created because of Star Trek (i.e. "Enterprise Car Rental" locations or a statue of "Vulcan" God of Smithing would not be accepted).
