The blue skies couldn't last forever.

A fog as thick as Russian borscht rolled into the mountains above Sochi on Sunday night. From the vantage point of the relatively low-altitude bobsled track, the gondolas heading up to the cross-country center and alpine venues disappeared into the clouds.

The weather is creating all sorts of problems for Olympic planners. A men's biathlon race was postponed Sunday because of low visibility. It was postponed again Monday. (The women's race was still on track for today.)

As The Associated Press notes:

Most people know Abraham Lincoln for his achievements as president. He issued the Emancipation Proclamation and held the nation together through the trauma of the Civil War. His Gettysburg Address is one of the best known in American history.

But what you might not know is that Lincoln cooked.

From his childhood to his days in the White House, food played an integral part in shaping Lincoln's life, food historian Rae Katherine Eighmey tells Tell Me More's Michel Martin.

Ralph Metcalfe and Jim Ryun sprinted. Bill Bradley and Tom McMillen dribbled. Bob Mathias ran, tossed, and jumped. Wendell Anderson defended. Ben Nighthorse Campbell judo chopped.

The seven athletes competed in different Olympic sports and in different eras, but they had one thing in common: they all ran for Congress and won.

Jean Leising admits she's no expert on brain development, but she still hopes to do something about the way kids learn.

Leising serves in the Indiana state Senate. Last month, she convinced her Senate colleagues to pass a bill that would restore instruction of cursive writing to the state's educational standards — the set of skills and knowledge kids are expected to master in each grade level.

Even in the email age, teaching cursive might be a great thing. But when legislatures impose mandates on instruction, professional educators get nervous.

Mark Twain once said: "If you don't like the weather in New England now, just wait a few minutes."

The online magazine Ozy covers people, places and trends on the horizon. Co-founder Carlos Watson joins All Things Considered regularly to tell us about the site's latest feature stories.

This week, Watson talks with host Arun Rath about a new texting service that promises tight security. While Snapchat has become a popular way to text photos that disappear after a number of seconds, recent hacks have raised questions about its security. A service called Privatext provides an alternative that has gained interest among some professionals.

A federal judge in Virginia struck down that state's voter-approved ban on same-sex marriage this week. It's just the latest in a string of similar rulings in conservative states, and it indicates that the strategy for winning marriage equality in federal courts is moving faster than many had expected.

In her ruling, U.S. District Judge Arenda Wright Allen said Virginia's ban on same-sex marriage is unconstitutional because "core civil rights are at stake." She compared the case to the landmark 1967 Supreme Court ruling recognizing interracial marriage.

The Deep South has been shaken up this winter in more ways than one: First, there was the unusual ice and snow and the ensuing power outages. And now, an earthquake.

The late-night 4.1 temblor, with an epicenter about 150 miles northwest of Charleston, was not strong enough to do any damage, but it did rattle folks in both South Carolina and Georgia.

According to the U.S. Geological Survey says the quake struck at 10:23 p.m. ET Friday night.
