Just a quick entry, but an important reminder:
Check your bolts!
I didn't ride in yesterday because after I got all my bike clothes on and started to wheel my bike out the door, I saw everything on the rack wobbling.
Upon investigation, it was missing the rack bolt on the top right.
Upon further investigation it was also missing the bolt on the bottom left.
I should have checked everything when I noticed the water bottle cage was coming loose, but alas, I did not.
So just a reminder: Check the tension on all the bolts periodically!
