The last month or six weeks have been awesome times for bike riders, at least in these parts. The bike racks at the office have been packed, and it seems you can't go anywhere without seeing other cyclists. (I'm happy to say that as a general rule, I haven't encountered too many of 'em riding down the wrong side of the road!)
No doubt the pump price has been one of the motivating factors.
(I heard a guy on the radio - an "expert" - declaring confidently that gas would be back around $2.50, most likely by July. And I breathed a sigh of relief that he isn't managing my retirement fund! I'll be surprised if the price is ever again south of $3.50.)
In years gone by, the spring bicycle-burst usually comes to an end around the middle of June, when temperatures start getting above 90 on a routine basis. Folks who can't ride when the temperature is below 60 or so typically can't tolerate heat, either. It will be interesting this year to see which is the stronger motivator - the wallet or the thermometer.
