River cruising resembles train travel: you journey from Here to There but don’t have to do the driving yourself. One thus experiences the journey. (Flying lacks this: one experiences only the point of departure and the destination. The experience of travel disappears, lost in abstract non-motion at 30,000+ feet.) Our afternoon cruising capped our morning in Speyer, just right for my still-recovering wife. Once moored at Rüdesheim, we chatted with the local ducks and enjoyed fine beverages. For me, that included this delightful Schwarzbier from Köstritzer.
