collisions

More than three thousand women are expected to swim the half mile, bike the 12 miles and then run, jog or walk the final 3.1 miles.

Commentator Susie Cohen says she considered running a bore, cycling a chore, and swimming done best without collisions with fish or fellow swimmers.

Add increasing age and decreasing time, she pretty much convinced herself to never try a triathlon.

The city plans to install nine red light cameras throughout Austin this semester. Officials expect the cameras to go online on May 1, said Gene Acuña, a city spokesman.

The city's Public Works Department narrowed down a list of 20 intersections identified as having the most collisions in 2006 and 2007 caused by someone running a red light, Acuña said.

Moons like ours - which are formed in catastrophic collisions - are rare in the Universe, astronomers say.
