Thank you - John Loudon McAdam!

I've installed the Answer Bar from Answers.com. In it's spotlight today it says: "Thanks to John Loudon McAdam, born on this date in 1756, we travel along smoothly-paved roads. A Scottish engineer, McAdam set himself to trying to improve England's poor roads. He came up with the idea of raising the path's surrounding ground and layering rocks and gravel which were then compacted with a roller, to form a "macadam" road. The first road in America to be macadamized was the National Road (later called the Cumberland Road), that eventually ran from Cumberland, MD, to St. Louis, MO. " hmm... lets start the day thanking John Loudon McAdam today...
