You commute on days when forecasters are calling for severe thunderstorms in the afternoon. ... which is about every other day here this summer. If I didn't bike every time the forecasters called for thunderstorms around here, I would hardly ever ride.

when family members will bring you old bikes they found in the dump because they know that it will make you happy and that you will surely use some part of the bike if not the whole bike.

You should change the oil in your car every 3500 miles OR once a year.

When your co-workers or classmates are stunned to find out you actually have a driver's license (and only because you needed to get it renewed)

When you're having a drink at the company Christmas party, and your coworkers are concerned that you've fallen off the wagon. (Since the only reason to commute by bike is because you've lost your license to a DUI.)

when the local traffic officer that I've known for 30 years, stops me on the road to make sure I have a drivers lisence

You've grown impervious to others assuming why are not driving a car.

"Must've had a couple of DUIs, poor guy..."

I think that fits under the "You know when you are a hoarder when..." thread.

+1.

that's the boat I am in

On a rare day I drove to work (Dr appointment) there was some debris in the road & I started to signal the " bike" behind me :-) !

When everyone at local bike shop asks how far you rode today knowing its a number higher than 50km. I didn't think I rode that much, but it seems 1200km or better a month is more than 99% of the local bike 'club' members ride in 3 months. That and when you sell your motorcycle and use your scooter as a 'no parking' barrier because you can ride to places faster on a bicycle anyway.

Good point there

agreed!!!!!!!!!!!!!!!!!!!!!!!!

You are the only one who cares that the motorcycle people are parking at the bike rack...

The only deer you've hit has been with bike...

You forget your pants and rather than just buying new pants across the street, you bike back home...

...when you had to drive to campus and at the end of the day walk around campus for 20 minutes searching for your bike.

When you eBay your truck to buy another bike

when your commute by car is 35 miles each way, but you sell the car anyway and say "WTH - I can do this every workday, even through Chicago winters".
.

that's beyond hardcore

Train helps to cut the biking down to 30-some miles each day.

When your boss has to tell you which days to bring the car to work for errands.

When you walk outside in the Texas summer and say, 'Eh, it's not that bad'.

This actually happened to me... October of 2010. I'll tell the story sometime - it was kinda traumatic!!!

I see that and figure "if I time it right, I should be just fine."

Just take a bag with a towel and a change of clothes and its all good.
