I wish I had time for a 30 mile bike ride.
You know how long it takes me to ride my bike to work 11 miles? 40 minutes. Know how long it takes to drive? An hour. I hate people with the excuse that "[they're] too busy!" Spend the $125.00 on a cheap bike and get the fuck out there. Or buy a used one for $25.00. Or get one for free at a police auction. Oh wait, then you wouldn't have an excuse anymore, sorry.
