Oh man, Pripyat? As a fan of the STALKER series (and Metro, although that has less to do with Chernobyl), I am officially jealous.
I can reccomend a visit! Although be sure to dress warm in winter (the cold could have literally killed us)
The best part, the guides are used to boring scientists and academics who follow the rules anyways. Rules like, dont touch the floor, dont touch the outside of buildings, dont eat the snow...
When they get a group of students, the rules fly out the window! Theres a pic somewhere of me sitting in the bumper cars near the ferris wheel :3
