As we wandered down Main Street, taking in the sights and sounds of Heidelberg, we passed countless cafes filled with people enjoying a leisurely lunch and soaking up the late May sunshine.
We admired the many soft pastel colored houses with window boxes bursting with color. We noticed that the flowers seemed mature for May, more like what you would expect in July. That is because Heidelberg has its own microclimate. It one of the warmest places in Germany, so flowers bloom earlier here.
