Of course that "something" is a bicycle. Or, more specifically, "bicycles" if you read closely. Because how can you live with just one bicycle? Does a golfer have only one club? Of course not, he (or she) has a bag full of tools to chose from for all conditions. As do I. Several. Nine to be exact, along with a mental list of a few more that I'd build up if the budget and space allowed.
