This may just be a small local thing but...

I'm rather embarrased about this, as I live just down the road from Boulder,CO. But, most riders I know in CO haven't heard of this maker.....

Lately I've been finding a few "Boulder Bicycles" and passing on them because they didn't look terribly special. A few of them were definitely vintage though, unless they just weather really poorly.....
I passed on one the other day for a vintage Muddy Fox MTB, my first M Fox, that was for sale next to it, but am thinking about going back for the Boulder.....

I think that the only one that I have seen outside of Denver is posted in our "Vintage MTB" thread (Elev12K ??)
