Having gotten an inexplicably decent sleep, I was out and ready to stroll around Frankfurt with little difficulty, at least as far as I remember. That is, except for the fact I had to go back and get my glasses just as the others were leaving. By the time I was back, they were gone; I’d told them to go on without me, but I didn’t expect them to be so far ahead. I walked at a pace substantially quicker than my usual, and never quite caught up to them on the way. That probably wasn’t helped by a couple photo detours.
Once I’d reached their destination, Frankfurt Cathedral, however (which they graciously supplied a link to in the group chat which I could plug into Google Maps), I found them standing around. Apparently, I’d arrived just a couple minutes before the sightseeing was about to start. I’m glad I was on time, because the Cathedral was just as impressive and nice to look at on the inside as the outside.
After that, we began to simply walk around Frankfurt, as I took pictures along the way.
The protruding center part is actually another building, behind the white one. What unfortunate placement… 
I didn’t realize it as I walked across, but we went across the Eiserner Steg, a bridge famous for it’s staggering amount of love locks. I wouldn’t have recognized it was a famous bridge had a good friend of mine not noted it while I was texting her. While everyone else was getting lunch, I took a detour back down there to look at it again, appreciating it a little more this time.
This would normally be enough to wrap up a whole day for me, but we had another event in store for us; a reception with the Mayor of Eltville am Rhein himself, Patrick Kunkel. I only learned of our shared name about two-thirds of the way through said reception.
Before we attended that, however, we had to get there, and once we did, we had plenty of time to spend until the reception. Me, Mike, Stephen, and Volker stopped to get ice cream first due to the sweltering heat, and the rest of the time I spent doing nothing by the river, which beat back the heat significantly with its cool breeze. I drifted here and there, loitering and lounging until I came to settle at a drinks place where everyone else was until it was time (which I did not take any pictures of).
The castle we walked into (yes, a castle) was positively full of flowers, ones I took many, MANY pictures of, but I kept only the best ones. Here they are;
The reception involved a short tour of one of the towers of the castle, from which we had a nice view, plus a few historical exhibitions within that I was too knocked out by heat to care about. I took pictures of the view, but they were through windows and not very remarkable. It was startlingly cool inside, to the point of being downright chilly. I joked the mayor was hoarding all of the cold air for himself.

Afterwards, a miniscule “meal” of sorts where we were served champagne and pretzels with a special cream cheese to go with them. I did, in fact, take a couple sips of the champagne, but promptly decided it didn’t taste very good and I’d much rather have a couple glasses of water to combat the ever-present heat. The trees and coming dusk helped, at least. I can, however, technically say that my first drink of alcohol was in a big flower garden castle behind closed doors with a mayor that shares my name, overlooking a pretty river.
