With The Light Of This Day

Today the temperature went over 40F.  Yesterday it came close to that.  For the first time this year, we've had consecutive days on which the temperature rose above freezing. 

As a result, all of the ice and much of the snow that had accumulated since Christmas were gone.  So I rode to and from work for the first time this week.  It might be the last time, too, as the temperature is supposed to drop by twenty degrees tomorrow and we're supposed to get another snowstorm.

Last week, one of the office assistants asked how I rode to work.  I had to think fairly hard.  I actually have three or four distinct routes, and a couple of permutations of each one.  I don't think much about which way I'm going;  somehow I just know where to turn.  In a similar fashion, lots of passengers know, without seeing any signs or hearing any announcement, when the train is pulling into their station.  Sometimes the passengers don't even have to see the station, or anything around it.  

What guides them to disembark at the right stop?  Is it some sort of internal clock?  Or some other cue?

To tell you the truth, sometimes I'm just navigating by nothing more than light.  Somehow the glare of signals and the way in which the day's light fades--or grows brighter--is enough for me to know which way to go.  Sometimes.

They're Coming Along For The Ride Now

I haven't made a habit of checking the statistics about my blogs.  But today I took a peek. 


It seems that during the past week, one of my early posts on this blog has been viewed more times than any of my other posts has been in the history of my blog.  In fact, that particular post is now the most-viewed in the history (such as it is) of this blog.


I wonder why they're all reading "Edvard Munch Comes Along For The Ride" now.

Takin' It Slow In The Snow

When there's snow on the ground and ice on there road--the conditions we've had here since Christmas--you ride more slowly.  Of course, it makes sense, especially if you ride in the dark, as I sometimes do when I'm riding home from work.  There's nothing like hitting a patch of ice you didn't see when you're pedalling at 20 mph!


Even though I know it's sensible to ride more slowly in the conditions we've had, I don't make any effort to do so.  Somehow I just find myself pedaling, sometimes, as if the cold air were turning into molasses.  I wonder:  Does cold air slow us down?  Or is it the somnolence I often feel on winter days?  The latter makes some sense:  After all, most primates move more slowly--if, of course, they're not hibernating.  Does it have to do with the shorter days?


Or maybe it has to do with the fact that, about this time of year, I'm starting to lose whatever conditioning I built up during the summer and fall. 


Another good reason to cycle more slowly, I've discovered, is that brakes--rim brakes, anyway--seem to take longer to stop than they do in milder weather.  I wonder whether the cold surface of the rim has anything to do with it.  Or, perhaps, brake pads harden a bit in the cold.

If my hypotheses are correct, do they also apply to disc brakes?  I've never owned a bike that had them, and I've ridden them only a couple of times, never in the cold.  But those of you who've ridden them--or all of you scientists and engineers:  What do you think?


I experienced the inverse of what I described the first time I cycled into the Alps. Just outside of Pontarlier, I had just crossed the border from France into Switzerland and, on a descent about a kilometer into Switzerland,  I got a flat.  When I pulled on my brake levers, it took more and more force to get the bike even to keep the bike from accelerating, let alone to slow it down or stop it.   Fortunately, the turns in the road weren't especially sharp and  only one car passed me from the time I pedaled out of Pontarlier.  So, I was able to stop the bike not far from the base of that descent.  


When I took off the wheel, my finger glanced off the side of the rim as if I'd touched a frying pan.  And my fingertip throbbed red for the rest of the day.  


I wonder what riding in winter there would've been like.
