Biking is one way of exercising. It is a great hobby for oneself. A great family bonding too. I used to have a bicycle before when I was in the Philippines. One day whiles going back from Los Angeles proper to get our ordered foods, I saw a bicycle in a bike rack, it maybe a yakima bike rack (but not so sure as I was not able to read such as it was far, it cannot be read from afar) and it impresses me at the same time reminiscing the fun I had with my bike before. All I did was just smile and look at the bike on the car's back. Such a good feeling reminiscing the good 'ole happy memories, biking how many miles with friends in a cool outfit. ;-)
