I think that board and batten sheathing over cement block would be nice. I had wanted the building to look like a WW&F station, but that would require windows. I proposed fake windows (Sublette NM and Plymouth NH), but Zack said, "Women don't like windows." I explained that they were fake and how that was done, but he just repeated, "Women don't like windows," and walked away. I think he proposes small awning-style windows up high under the eaves, which is fine since we need windows, but I'd still like to add fake windows and/or doors to give a station appearance.
I propose that people consider the following examples that are nice: NH rest area northbound at MA line, ME rest areas at Kennebunk. It would be good to also consider examples that are offensive in appearance and odor: NH liquor store at Hampton southbound, ME rest rooms on I95N at Pittsfield. The ugly ones are concrete block with bare (porous) concrete floors.
