I'm a total newbie to OSM proposals and discussions like this one so let me
apologize in advance for this off topic post.

I'm still following along but I'm wondering how a person will ever see this
sort of detail in a map. I confess I mostly work on OSM so I can get
detailed and correct maps for use in a Garmin GPS in the areas I live and
work in, Alaska and Thailand primarily. I get all my maps from Lambertus at
garmin.openstreetmap.nl and while his rendering isn't perfect it serves my
purposes well enough.

Can one of you suggest a site where I can see details like those you
mention?
