In reply to Toerag:
I would not worry too much abut TBE, the risk is minimal compared, say, to travelling to Frankenjura by car. In all of Germany, there were some 3000 reported cases since the year 2000, with 1 or 2% serious complications or death. No point worrying about the vast majority of asymptomatic infections. Watch out for Lyme disease, though, screening for ticks in the evening does make sense (tick removal helps reducing Borrelia infection, but is useless against TBE, as the viruses are transmitted immediately).
Frankenjura is definitely a risk area for both diseases, but we have not died out yet, so overall it is not THAT bad (I grew up in cycling distance from the Trubachtal crags, and am still alive even though I definitely had my share of tick bites).
Funnily, a classmate from school who would not be caught dead doing anything outdoor related managed to catch both diseases from the same, single tick bite at a music festival near Erlangen.
