Thanks to June, I can see where Glenwood, HI, is available on an electronic map. So, I checked my copy of Mircorsoft's Streets & Trips and also found it there.
It is on the Big Island (Hawaii) on Route 11, between Volcano and Mountain View. Yet, the font (on my Streets & Trips) is smaller than the font level as is used for towns, indicating that it is something less than a town.
So, it appears that perhaps this is a community that could be considered a town, in which case, I'll concede the point.
My argument has been that a place does not qualify unless recognized by the United States Postal Service -- if we go by this, then Glenwood does not yet qualify.
Maybe we can get some info on this community from an Hawaiian resident. Anyone living there who's reading this?
Yet, as regards to Glenwood being the answer to the question. I don't see a Glenwood, Alaska, so perhaps Glenwood, Hawaii is moot. "Glenwood" is not the answer.
Cordially,
Russ
