Woohoo! Back on the bike after I picked it up from the shop yesterday. Riding in today was amazing. My gears were shifting beautifully. Normally, since I adjust them, they function, but not that well! Of course, the new chain and cassette might have something to do with that.
The last two days were relatively traffic-free, which was good because I was in a car. Today there were cars everywhere, but I could get around all of them.
