Is this waterstream large to deserve boat: tag at all? It looks like a tiny stream to me on the imagery.

Is this house Jalovcová 1 (which is what we have here) or Husova 10 (which is what http://www.u3r.cz/ claims to be at)?

This should be Avenue De Montmorency

there is 40 kmh speed limit on the bridge

According to Google Maps, Mapy.cz and http://izgard.cenia.cz/dmunew/viewer.htm claim that the name of this street is "Zd. Nejedlého".
