Adjusted my rear derailleur last night, per SRAM's manual. I was careful, honest.

Chain skipped this morning, everything I did made it worse, and it finally came off and jammed both wheels.

Got it back on, couldn't figure out how to undo the bad adjustments, chain was skipping all over the place. I am now back home with my kids. Preschool is cancelled and I have grease everywhere.

Apparently rear derailleurs are next on the list of things to learn more about.
