Once we decided to celebrate Women's Day (8th of March) in Sablino, where the famous caves are located. Strictly speaking, they are actually not natural caves, rather the old sand mines, but people often call them "caves". We had visited two mines: one called "Three-eyed cave" because it had three entrances, and the other one called "Trouses" because its part with the two parallel blind-ended passages remained trouses. On the way we had met a dog, which accompanied us during our underground trips.
