Below is a very detailed travel advisory I recieved from US Army Europe. Please, please, please be aware of the upcoming NATO protests. They are expected to be violent.
Travel Guidance - NATO Summit
Situation: Authorities expect 15,000 to 25,000 anti-NATO protestors to hold demonstrations in Strasbourg, France and Kehl and Baden-Baden, Germany between 1 and 5 April, as the NATO Summit takes place. Naturally, demonstrations are not limited to these locations, but these are expected to be the largest. Law enforcement anticipates some level of violence associated with these protests, including rock-throwing and improvised firebombs. Many protesters are identified as being distinctly anti-U.S. and could harass or assault U.S. personnel in the vicinity of the summit. Police plan to restrict vehicular and pedestrian traffic in and around these cities for the duration of the summit.
Recommendations: Recommend avoiding travel to the above locations from 1-5> April.
