how does the Museums on Us work ?price ? time? is it only the first week end of the month ? thank you

The museum is open Thursday thru Sunday only from 9:30 to 5 it is $55 per person also a great experience

Times and days each museum is opened varies, especially since the pandemic. Each state may have different requirements. Pricing also varies some museums are free, some others have a fee and offer memberships. Some offer free parking, others charge for parking. Best thing to do is research online the museum you wish to visit or give them a call.
