Best bets this weekend include Second Saturday Seminar and the Epic 4x4 Quest.

Animas Museum will host the Second Saturday Seminar at 1 p.m. Saturday via Zoom.

Durango’s history as a Wild West frontier town is full of stories of cowboys, railroaders, outlaws and “soiled doves.” Bessie Rivers was a legendary madam, and Hattie Mashburn was a business woman, in an era when that was unusual. Meet Rivers, the notorious owner of a “sporting house,” and upstanding businesswoman Mashburn in a presentation called “Madame, not a Madam.”

The webinar will be recorded. Cost is $5 and will benefit the Animas Museum’s online programming.

To register, visit www.animasmuseum.org/events.html.

The Epic 4x4 Quest second annual Maximum Offroad Adventure Backing-the-Blue event will take place from noon Friday to Monday in Farmington.

Participants will face challenging trails that will be revealed at the start of the event. All makes and models of vehicles may participate.
