Sorry, in English, my German skills are bad, especially in the morning. When you register/log in you can see the coordinates directly. Or you can get them from the google maps URL, but that is a hassle. Unfortunately it is only offline. I'd suggest getting a prepaid sim anyways, makes things so much easier (avoid T-Mobile though, bad coverage). But maybe someone will come up with an offline list.

You can get free internet on any Main Street, AnyTown USA. Even if they don't have MacDonalds, Starbucks and similar, there will be a laundromat, coffee shop, motel, safeways, Home Depot or ..... that will have free internet available via an unlocked hotspot.

If you install Scrapbook plug in on Firefox you can get on-line, look up a few boondocking sites along the way and scrapbook each detailed page for likely sites.
