Tundra_Man, you have my sympathy. Many years ago, I had crippling sciatica. I was young, and I had surgery to correct it. We know more now, and maybe I wouldn't have had it, but I don't regret it. The pain lasted for months, and I couldn't think well enough to work. I hope you find whatever it is that will heal you.
Today's morning commute was nice. Rather than riding Citi Bike, I took one of my own bikes. Citi Bike makes sense most of the time for a 2-mile commute because I don't have to take care of lights, and I don't have to lock the bike up. I recently replaced the fork on my old 1975 Viscount. Years ago, I converted it to fixed gear. The bike is very light, and it's a great beater bike. I wanted to see how it handles since changing the fork can make it different. I think the geometry is close enough to the original so-called "death fork" so I'm happy about that.
I got to work in record time. 11 minutes from outside door to outside door. It also took less physical effort so I didn't get too hot.
Coming home was similar, but I made a bone-headed move, merging into traffic from one street to another while a big truck (who had right of way) was already in the intersection. He honked a few times to tell me how dumb my move was. I bet I scared him. If there had been an opportunity to apologize, I would have done so. I do that kind of thing. I can imagine how he might have felt.
Here's my beater bike inside my apartment.
