First commute didn't happen. I have my regular job and a private practice that I do out of my job location, but on my own time, and I ended up scheduling a 7AM session. Since I don't have the timing figured out yet, I wasn't willing to risk being late or not having time to clean up before. Friday will now be my first commute.

I'm in the same situation as you with the tire thing. I went to a flat tire clinic two weeks ago, but it was all observation. I have yet to practice fixing one, and I'm nervous to try, but know it's better to try it out now and fail rather than try it out for the first time on the road.
