51MPH, sweet. I really enjoy the few times I have a great tailwind or on a nice downhill and I can actually pass cars (I know, not always the brightest thing to do, put it does feel great). I noticed the hills this winter got a little tougher than realized I had packed on a few extra lbs to "protect me from the flu season". Once the lbs were shed ( this month) the hills returned to their normal nasty self.
JCM - yodeling down a hill interesting, I've chortled down a hill, sang Steely Dan down a hill, screamed down a hill, but never yodel'd, will have to give it try tomorrow
