Adam Pieniazek is enjoying a nice bike ride on Columbia Road in Dorchester when some fat putz in a rustbucket begins slamming his horn and demanding Pieniazek pull over to let him through. Pieniazek did pull to the side, but didn't stop, which only further enraged the guy. He reports that the guy, who appeared to be Puerto Rican or Dominican, finally exhausted his supply of expletives and yelled:

Do you know where you are white boy?

Pieniazek, a Dot rat, finally lost him at a light - but not until he took down his license-plate number. He wonders: Should he use the handy motorist-complaint form he downloaded?

Because he was awfully calm after a woman hit him while he was riding his bike on River Street in Hyde Park last week:

He fell off his bike and suffered a small cut to his ankle, but told the flustered motorist to "just get going, and don't be late for work," Joyce said.

Memo to Massholes in delivery trucks: You might not want to throw bananas at bicyclists when your company's name, phone number and Web site are all listed on the side of your vehicle. And, yes, we're looking at you, Boston Organ and Piano.

My friend took the time to share it with his friends, and so I am taking the time to share it with you! The following is a copy of his post.

Hello friends,

Late Tuesday afternoon I was riding my bike and was hit by a cab. I was in the bike lane, going 20-25 mph when out of nowhere the cabbie took a hard left, cut me off and I hit him head-on. It happened so fast I didn't have time to brake, swerve or yell. The only thought I had was "#%^&, I'm dead!"

Mike Ball is all in favor of bicycling, but says Mayor Menino needs to stop dressing like a grumpy Care Bear:

... That's doubly unfortunate in that he was doing something vaguely athletic and he was quite jolly at the time. ...

Don Martelli writes the photo of the biking mayor reminds him a bit of that infamous video of Mike Dukakis in a tank.

Mike Mennonno, normally an inveterate bike rider, is thinking of taking the T to work:

... Because the problem with encouraging more bicycle commuting before you've got adequate infrastructure in place for it is it may end up having the opposite of the intended effect. Add to that that there are plenty of Massholes among the ranks of cyclists, too, and Bike Week in Boston is a recipe for anarchy. ...

Oh, yeah, Masshole cyclists.

Casey reports on her first bicycle commute:

... When a Prius passed me, I laughed. "You think you're green? Ha!" ...

Adam Pieniazek reports Bike Week news, including:

... Yesterday I was biking through Cambridge and Somerville, via Hampshire and Beacon Street and noticed a new feature on the Beacon Street/Somerville side of the trip. Bike lanes! ...

Citizen Smith ponders a "Temporary Bike Rack 2 Hour Limit" sign at a Harvard building:

... Is there some sort of crazy bike parking going on where bikes are just piling up all over the place and people are leaving them there for days, weeks, months? If this is the case, which I don't think it is, because I've been walking by this for 4 years, and I assure you I would have noticed this rampant abuse of bike parking, but if it is the case, have you considered adding to the 2 small bike lock up bars that are there? Because there's plenty of room here. You could get two more racks in, easy. ...

Sheldon Brown, well known in bicycle circles both locally and nationally, died Sunday, 63.

Chuck Tanowitz recalls interviewing Brown after he put his Harris Cyclery in West Newton on the Internet back in the mid-1990s. He adds:

... I also used his advice on teaching kids to ride in order to help my 8-year-old finally learn to ride a two-wheeler (the key: removing the pedals and lowering the seat). ...

John Daley is liking the proposal to shut Storrow Drive on Sunday mornings:

... It's a good idea. Every Sunday will be the Fourth of July. ...

Some of us, of course, would prefer to see Storrow shut permanently.

Tracy the Astonishing took the above photo yesterday. One can only imagine what it looks like now.

Who knew there were freight bikes? Larsks reports the Dutch Bike Company has rented space at 50 Tufts St. in Somerville and hopes to open for business by February, selling what look like pedalable wheelbarrows.
