On the corner of our block is a bus stop for bus 350 which goes from there to the Paris Air and Space Museum. We went to the Paris Air and Space museum today - Friday March 8th. But we did not leave from the bus stop on our corner. No. We followed the instructions on how to get to the stop from Gare du Nord not realizing we were going out a half mile to come back a half mile another way. The museum was great - lots of flying machines.
