Was this story just another web hoax? Yes, says subscriber Mary Mycio on the "e-POSHTA" Ukrainian mailing list, re-posted on Neil Gaiman's website.
I am sorry to report that much of Elena's story is not true. She did not travel around the zone by herself on a motorcycle. Motorcycles are banned in the zone, as is wandering around alone, without an escort from the zone administration. She made one trip there with her husband and a friend. They traveled in a Chornobyl car that picked them up in Kyiv.
She did, however, bring a motorcycle helmet. They organized their trip through a Kyiv travel agency and the administration of the Chornobyl zone (and not her father). They were given the same standard excursion that most Chernobyl tourists receive. When the Web site appeared, Zone Administration personnel were in an uproar over who approved a motorcycle trip in the zone. When it turned out that the motorcycle story was an invention, they were even less pleased about this fantasy Web site.
Because of those problems, Elena and her husband have changed the Web site and the story considerably in the last few days. Earlier versions of the narrative lied more blatantly about Elena taking lone motorcycle trips in the zone. That has been changed to merely suggest that she does so, which is still misleading.
If so — ah, well. C'est la web. The photos are still amazing. Link (Thanks, chupacabra)
