There is no coast closer than a 5 hours drive from here. But a one hour drive at the weekend got us to Mainz on Saturday, very close to the place of the confluence of rivers Rhine and Main (despite the spelling, they actually rhyme).
Besides seeing friends again (how we had missed that!) and running and walking and chatting, we saw ships going by. Sometimes two of them meeting in the middle of the river.
It quietened down towards evening, and then HE came along:
The HE 7 is the patrol boat of the Hesse river police, stationed in Wiesbaden.
