Well, if you live 15 miles away and you ride your bike, you will be one fit lad or lady in two months. Well, what if you have shopping bags? I live downtown and I cant remember the last time I had a shopping bag from a store downtown, there are only 5 clothing stores, 10,000 bars and about 9 restaurants. In the hypothetical situation that you did have a shopping bag, buy a basket or rack for your bike.
