Quoted from Ferd:
Is the Ann Arbor Michigan pinball museum open on a weekly basis? The museum of pinball (Banning) is only open a few days a year. I believe they are trying to expand that but for 2017 I think its just the one weekend, not counting the tournament last week.
The VFW / Ann Arbor Michigan Pinball Museum hours are posted on the website linked above. While not open weekly, is there a particular week or day you'd like to visit?
