Beautiful morning and I was cranking along happily till I flatted 2/3 of the way in. Front flat so not a big deal to replace the tube. I was at an intersection and a commuter stopped next to me waiting on the light. Nice guy, asked if I needed help and commented that it was an awesome day to be riding. Even with the flat, I had to agree with him. Fixed, aired up and on my way in a little over 5 minutes.
