Head to Triberg Locksmith, stopped there twice,one of the bigger towns in the forest,central in black forest pretty active place, food stops, hotels, good german roads and most of all all the cuckoo clocks you can imagine, try to come back with one and not some embarressing disease
If you get bored in the Forest with the teddy bear's picnic's,
Head for Rothenburg on the romantic road area, fantastic old style town, and would be my personal preference to black forest got drenched with rain last time in the black woods .
