Foundry Group managing director Brad Feld's bathroom buying continues.

The venture capitalist has endowed another men's room at the University of Colorado, this one in the Wolf Law building, the home of the Law School.

Feld also endowed a restroom at CU's Atlas building and the Dairy Arts Center in Boulder.

"I don't really feel like writing a check for a building, because they're too expensive, and the other stuff they give you isn't fun," Feld joked at the Boulder Denver New Tech Meetup, which hosted a brief ceremony announcing the donation.

While endowing a men's room inspires a steady stream of jokes, the donation itself is an expression of gratitude for the work CU has done to nurture the startup community, Feld said.

It also turns a trip to the john into a teachable moment. Outside the ATLAS men's room is a plaque reminding visitors to always be ready for good ideas, even if they come at inconvenient times.

As if we didn't already get enough "Law and Order," this Saturday attorneys will be tutored in the finer points of courtroom protocol.

The nonprofit National Institute for Trial Advocacy in Boulder will be taking 52 lawyers from all across the country and firms of all sizes through its weeklong Building Trial Skills program. NITA's mission is to train and mentor lawyers to be competent and ethical advocates in the pursuit of justice.

And thanks to the generosity of Denver law firm Wheeler Trigg O'Donnell LLP, four public service attorneys will attend. WTO'D is covering the cost of tuition and travel for the public servants who represent those in communities of people who traditionally are unable to afford legal services.

This is only a test … .

Those good scientists at the National Weather Service will hold a test of the state's tornado warning system on Tuesday, April 17. (Also tax day this year, just in case you've been marooned on a desert island for the last 365 days and didn't hear the news.)

National Weather Service offices in Boulder, Pueblo, Grand Junction and Goodland, Kansas will issue test warnings between 9:15 and 10:30 a.m. that morning, and you may hear warning sirens.

Warnings also will be broadcast on local TV and radio stations.

The National Weather Service is a division of the National Oceanic and Atmospheric Administration, which has more than 900 employees at its federal lab site in Boulder.

On average, 50 tornadoes touch down in Colorado annually, according to the National Weather Service.

We don't know about you, but we've never heard a tornado siren. The most eerie sirens we have ever heard are the ones near Boulder Creek that the city of Boulder cranks up when the creek is running high.
