t17 c15 May 2 Worms 66k823 Mainz

Warm enough for the first day in shorts for a while.
Cycling up the left bank, I emerged from industry after about 10k, then continued on the Rhein embankment for most of the day.   Its surface was muddy, or rough chippings, or what finally caused the puncture: bricks with gaps.   Tried the almost parallel B9 road, but too dangerous: many trucks, no cycle lane.

River traffic becoming busy  - -  mostly Dutch barges (115m x 11.75m) punching upriver laden, or coasting down light,

plus a few tourist liners.

In Mainz I was directed to a decent altstadt hotel by a taxi driver.  
I relaxed with a beer in the sunshine and wafting blossom, by the Gutenberg museum

(Gutenberg bible:  1450s  first book printed by moveable type in the West.)

Later, observed the river bank evening strollers were heading in one direction, followed, and ended up at a wine festival.
