#9 - It'll snow the day after you take off your studs.

Seriously, I just got my new summer slicks yesterday and mounted 'em right after class. There was a bit of snow coming down last night but none of it was sticking, figured it'd be slop by this morning. Woke up this morning to solid black ice under half an inch of snow. It's been 40*-45*F every morning for the past two weeks, and I've been rolling studs on wet pavement the entire time waiting for my new tires.

I hate riding the bus.

Modified #3: that "slightly low" tire that you pump up a little before leaving late for work will last just long enough
that you're stuck in some crappy unlit area to swap in a new tube.

Had a few "murphy" commutes -- the ones that stand out, though, both involve rain (which I still love riding through); one was the morning commute that involved a pop-up shower, no rain gear -- Fat Boy doing the weather forecast said sunny and breezy all day, 15 minutes before I left the house. My shoes squished for four hours.

The other was going home -- on brand-new tires, picked up a bit of industrial wire about an inch long; at least the rain stopped by the time I unpacked the spare tube.... Hung the bike from a tree limb and did the fix.

#10 (aka Jim's Law of the Road): No matter how lightly traveled and well paved a road is, a car will likely pass you on the left as you encounter an obstacle on the right.

You will click the cable lock closed approximately 5 seconds before you realize you forgot your keys today.

(Clearly, Murphy can be thwarted by storing your cable in a 'locked' fashion, but who ever forgets their KEYS?)

TV Weather never gives me enough detail, and they always make very broad assertions to cover large areas. I need to know specifics for my route and commuting times.

I'd like to generalize this a little more:
Just when you think you've hit the bathroom for the last time before setting out, think again.
I can't remember the last time I said "Bye!" to wife and child, headed out the door, and didn't step back in again.

Corollary to all the above: If you're out on a perfectly trouble-free ride on a beautiful day with a tailwind then you've overlooked something catastrophic that may very well kill you if you don't pull over and terminate your ride immediately!.

On the day you leave your cable at home is the day you need to lock two bikes with one mini Ulock.


(this one almost happen to me, go figure)
You will get right hook while you are giving the birdie finger to the first driver who right hooked you.

Ha ha, I was in the same boat. Been the only day I've missed the last few weeks! Every Spring we continue to fool ourselves into thinking that *this year's* gonna be different!

A UK forecast saying "scattered showers" means that they will be separated by periods of heavy rain

I have given up on the precipitation forecast. I just plan to ride no matter what because I almost always regret not doing it. At least the temperature forecast is usually close enough to help me pick out my clothes the night before.

No matter how well you plan, one of these days you will spend a day at work a la commando.

+1

never eat the spicy chimichunga for lunch.

It will be dark and gloomy on your ride to work; the sun will come out as soon as you reach your destination.

While patching front tire, rear tire is slowly leaking air.

Nevermind. RogerB beat me to it.
