Thanks for all the great replies. My wife thinks I'm crazy because I went on a 30 mile bicycle ride yesterday and had a great workout at the same time. I tried to get her to go along with me, and well... that didn't go over very well! Besides using a treadmill for rainy days, and/or this coming winter months, I have found that riding a bicycle long distances really gets your heart and lungs pumping, as you try to maintain a steady 15 or 16 mph (24 - 25 kph). It's not as hard on the body as running a 10K in under an hour (best time: 58:15 -- and it took me days to recover!) I know we all appreciate vintage trumpets and cornets as seen in various sub-forums and posts from everyone. I also appreciate vintage '80s style road bikes with the old style, 27" gumwall tires, manual lever friction shifters, heavy gauge steel frame, etc... Those old bikes are built like a tank and keep on going. Check out my classic 1985 Fuji Del Rey, 12 speed road bike, that I picked up a number of years ago from a college kid (was his dad's bike - new in '85 - and once the kid graduated, he didn't want the bike anymore and the dad didn't want it back). I snatched it up for $100 bucks, if I remember right. Darn thing was still in MINT condition for being a 30+ year old bicycle!
