I'm confused, did they legally entered the Chernobyl Exclusion Zone? I was told that biking into the Chernobyl Zone, e.g., is forbidden due to the risk of contamination when you exit.<p>Edit: Indeed it was not. From Instagram, “we spent the night tiptoeing around razor wire fences, coasting through sleeping security checkpoints, and riding frantically away from some surprisingly alert and vigilant guard dogs.” This validates what I know from Ukraine. Entering the exclusion zone is a very lucrative touristic business, with prices around $100-200 for a single day trip in a group.
