Montana acquired its nickname of The Treasure State due to the rich deposits of minerals found here, though the name suits to describe its flea markets and antique fairs too! It is also known for its wide-open spaces and its cowboys, and the pride that Montanans takes in these aspects of their state is clear. Flea markets offer up windows into the past and there is no better place to delve into local history than at one of the state’s many regular events.
