I'm surprised no one mentioned it yet, but for those of us affiliated with the Boy Scouts this is our slogan: "Do a good turn daily".
I'm not quite at that speed, but on 12/21 I helped someone in Lowes parking lot who had 2 very low tires on his car. My compressor and about 20 mins. took care of that for him, enough for him to drive to the nearest tire outlet for repairs which probably saved him a tow or permanent damage to those tires.
No need to enter me into the contest - let someone more deserving win the prize.
Excellent thread however, a reminder to all of us that frequent acts of kindness are what keep us mindful of the less fortunate...
