Here in Tucson it's a very bike-friendly environment. All the major roads have bike lanes, as do many of the lesser streets. On weekends especially you'll see packs of riders all over the place. HOWEVER, among the thousands of bikers out here, there are several a**hats who ruin it for everyone else. I'm talking about riders who insist on riding two or three abreast, thereby straying into the car lanes. Or the individual who insists on riding his bike on the white lane line when he has six feet of empty pavement to his right.
