Dusseldorf Germany - the summer heat has arrived on the Rhine

Things have finally warmed up in Europe.  Beautiful day today but the keeps rising every day.
I got to the "Old Town Area" of Dusseldorf today.  Most of it was blown up during WWII.  They rebuilt on the same foundations so it still has the feel of an old European City.
Dusseldorf sits right on the edge of the Rhine River and, like every where else I have been in Germany,  is filled with bike paths to get your everywhere in the city.  And there are beautiful parks that fill the banks of both sides of the river - made for a great walk back to the hotel.
