Ok, I'll consider the tire change. How much do smooth tires cost?

I do enjoy riding, but live in rainy Oregon. It rains a good 150 days a year (or at least it feels like it!), so I don't really feel like trying to compete with that. I also (currently) ride in my work clothes, and my bike doesn't have fenders (?) so I'd have to buy special riding clothes, modify my bike to protect from spray, make sure I arrive early enough to change, wear a backpack and somehow try to not wrinkly my dress shirts and pants inside it, etc. Just a lot of inconveniences that I'm not sure I am willing to overcome.

We'll see - maybe I'll get addicted to it.

EDIT: For what it's worth, I LOVE driving. I have a Mazdaspeed Miata - a turbocharged convertible roadster - and it's an absolute blast to drive. I do some autocross with it too. As it is now, I really miss driving it daily, but am willing to miss out on it to save some money for now.
