Just [i]looking[/i] at singletrack, or even the faintest hint of a line, is enough to make me grin like an idiot.
Unconsciously shifting your weight around in the chair whilst watching mtb vids.
Inability to remember somebody's name, whilst recalling their bike in exacting detail.
Sad, moi?
[edit] ah, didn't notice SFB's post - nor have I read the latest STW.
Sad but I am always checking out passing bikes for something interesting.
I remember watching an episode of Drop-In and one of the guys was saying he had 'lines disease'. He said all extreme sports enthusiasts have it, skiers, snowboarders, skateboarders etc. It's when you're gong about your daily life, maybe driving along the motorway or sitting on the train whilst looking out of the window at potential lines and getting all excited.
Trying to manual the car over speedbumps (sadly doesn't work)
Unclipping from the accelerator pedal.
Agree about lines disease. I can't walk anywhere without looking for stunts (urban), or picking the line I'd ride (country).
Not recognising people you've ridden with for years because you've not seen them in civvies and without a helmet.
I have a habit of looking at urban environments wherever I am and thinking about it in terms of whether it would be good to ride.
I've been off the bike for 2 weeks now while I finish my Master's dissertation. Still, everytime I walk past it in the hallway I end up tinkering for no reason. It may have happened that I ended up sitting on it once or twice to 'check whether I should perhaps raise the stem a little'. Handing in today though so I've already got rides arranged for this weekend. After that I'll be snowed under putting together a doctoral proposal.
I was with my (female) boss the other day at a train station. I find myself having a good long stare at this girls very nice looking Cotic Soda race bike (had race plates on it etc) but my boss accused me of blatantly checking out her bottom!
It was only after she incredulously accused me of this that I notice the girl in question really did have an absolute peach of an ass.
