Changes

Also you can get to a gas station on the A1 heading to Denmark by catching the S-Bahn to the stop called Wilhelmsburg. From there catch bus number 13 to the stop Kirchdorf süd, which is the last stop on the route. Walk up past where the buses turn around, follow the highway to the right, go under the highway by way of the tunnel, and there is the gas station!

Take a ride or take the S-Bahn A1 to Quickborn station. There take the bus 594 in direction to "U A Norderstedt Mitte" and stop at Heidefriedhof station. There you can maybe buy some flowers (a very nice old women offered us some informations -okay it was wrong- and a rose). You should see a bridge across the highway, cross it, and take the first the small street on right. You will feel you are lost in the country side because after 200 meters, this way doesnt look like a street anymore. Nevermind, go ahead, go ahead go ahead and on your right you will see a oil station. We needed less than five minutes to find a driver to Denmark :D
