Well, I was very thankful for the aero bars this morning as I used up all the strength in my right arm setting up flags for the boy scouts (fund raiser, I had to drive 58 pieces of rebar into the ground with a sledge hammer to hold as many flags up). Nice warm morning too by the time I started heading off to work. Computer said it was 100 degrees at 9:00 AM, even allowing for bike computer temp inflation thats still pretty warm for that time of morning.
