I don't think there has a been a music store in Marysville in my lifetime.

Hmm .. 1987

Pine Grove location is literally a few seconds away once you get off the bridge, and you get multiple chances to tun into the 'mall' area (of which PHMC owns 80% or more now)so hard to miss if you are looking for it.
The store on Military was much smaller and a little farther away, maybe 10 minutes like you mention.
I'm guessing you went to the old store, but if so, that was likely before 1987 .. getting old stinks when trying to remember details/dates.

The year suggests the new store, but the travel time suggests the old store.
Can you describe the inside of the store?
Was it pretty small, or big?
The two locations are hugely different
Cool story ..
My dad came home one night and at dinner was talking about the weird experience he had that day.
A Limo had pulled up in front of the store
He said four long-hairs got out and came in, checking out the guitars and basses.
Then only bought some strings and left.

KISS was playing McMorran that weekend .. I put 2 & 2 together and explained to him what had happened .. and reprimanded him for getting no pictures, even though there weren't cell phones back then, so not so easy
But those were the days when getting a picture of the band without makeup would have been a pretty big deal.

I do not work here, but the benefits are still awesome
